Case 1 – Cost-Volume-Profit Analysis (Assignment 1 – 20% of final grade) Janet Jennings is the general manager for Mercashoe Store. She is currently working on a major promotional campaign. Her ideas include the installation of a new lighting system and increased display space that will add $24,000 in fixed costs to the existing fixed costs. In addition, Janet is proposing a 5% price decrease ($40 to $38) that will produce a 20% increase in sales volume (20,000 to 24,000). Variable costs will remain at $24 per pair of shoes. Management is impressed with Janet’s ideas but concerned about the effects theses changes will have on the break-even point and the margin of safety. Information provided: A. Rental expenses for the store: $5,000 per month. B. Janet has a salary assigned of $60,000 per year. C. The store has a sales manager who earns $45,000 per year. D. There are three salesclerks who have a salary assigned of $25,000 each per year. E. Social security expenses for each the employees represent 30% of their salary. F. Utilities expense: $600 per month. Instructions: 1. Compute the current break-even point in units and compare it to the break-even point in units if Janet’s ideas are implemented. 2. Compute the contribution margin ratio under current operations and after Janet’s changes are introduced. (Round to the nearest full percent). 3. Compute the margin of safety under the two proposals. 4. What is the operating income under each scenario? 5. Prepare a CVP (Cost-Volume-Profit) income statement for current operations and after Janet’s changes are introduced. 6. Prepare a Cost-Volume-Profit graph under the two scenarios. 7. Prepare a report explaining and justifying whether Janet’s changes should be adopted or not and provide suggestions supported by the information provided above. Show your work in Word of Excel

Question 13

We define the letters 'a', 'e', 'i', 'o' and 'u' as vowels. We do not consider any other letter as a vowel.

Write a function named initialVowels() that returns a list of words in a body of text that begin with a vowel.

Include both capitalized and lower case instances of the vowels.

A word should appear in the return list at most once, no matter how many times is occurs in the input string.

Input: a string that consists of words, separated by spaces

Return: an list of words in the input string that begin with an upper or lower case vowel

For example, the following would be correct output:

>>> mlk = 'Our lives begin to end the day we become silent about things that matter'

>>> print(initialVowels(mlk))

['Our','about']

Question 14

The three words 'a', 'an' and 'the' are the only articles in the English language.

Write a function named countArticles(). Hint: Count both capitalized and lower case instances of articles.

Input: a string, named sentence

Return: the number of words in sentence that are articles

For example, the following would be correct output:

>>> theFlea = ['The flea is a mighty insect']

>>> print(articleCount(theFlea))

>>> 2

Question 15

Write a function named pluralCount() that takes two string parameters.

The first parameter is the name of an input file that exists before pluralCount() is called.

The second parameter is the name of an output file that pluralCount() creates and writes to.

You may assume that the input file is in the current working directory and you should write the output file to that directory as well.

For each line in the input file, the function pluralCount() should write to the output file the number of words in the line that end in the letter 's'.

For example, if the following is the content of the file foxInSocks.txt:

Look, sir. Look, sir. Mr. Knox, sir.

Let's do tricks with bricks and blocks, sir.

Let's do tricks with chicks and clocks, sir.

The following function call:

inF = 'foxInSocks.txt'

outF = 'foxRepLines.txt'

pluralCount(inF, outF)

should create the file ‘foxRepLines.txt’ with the content:

0

Using Virtualbox in Debian, write a simple program (a single .cpp file) in Linux shell C++

Rules:

-Use fork(), exec(), wait(), and exit()

_______________________________________________________________________________________________________________________________________________

-A line of input represents a token group.

-Each token group will result in the shell forking a new process and then executing the process.

e.g. cat –n myfile.txt // a token group

-Every token group must begin with a word that is called the command(see example above). The words immediately following a command are calledarguments(e.g. there are two arguments for the catcommand above).A command may be followed bynone, one, or more argumentsas the command allows to have.

_______________________________________________________________________________________________________________________________________________

Shell Commands To Test:

ls: a token group containing one token(i.e.a command)

ls -l: a token group containing two tokens (i.e.a command and an argument)

sort infile: a tokengroup containingtwo tokens (i.e.acommand and an argument)

dir: a token group containingonly one token (i.e.a command)

sort –dinfile: atoken group containingthree tokens (i.e.a command and two arguments)

cat infile: a token group containing two tokens (i.e.a command and an argument)

Lines of input are interpreted once their tokens are correctly extracted.Your shell should first print a # sign to the screen representing a prompt and wait there until the user types in a command. Your shell then spawns a child process to carry out the command.When yourshell finishes processingthe current line, it prints a # sign again to the screen waiting for the user to type in another command.This process is repeated until the user presses Ctrl-C to terminate your shell.

-Every command is to be interpreted as a valid Linux executable to be executed.

-All commands are assumed to be in the current directory.

-After interpreting a command, the shell should wait for the forked processto terminate before processingthe next line of input.

The program should be able to extract tokens from each input line entered by the user. If you have problems with extracting tokens from input lines, you may use the C++ library function strtok() to do it.

CH 7: Entrepreneurship Case BBG 101 -- Hart

One of the biggest challenges for entrepreneurs is getting the word out about their new venture. Perhaps that's why entrepreneurs have embraced social media as a communication tool.

If used skillfully, many believe, social media can help level the playing field between small businesses and their giant competitors. David avRutick, co-owner of Folbot, a small kayak retailer, claims that without Twitter, he wouldn't have as many sales as he does. “You can't buy that kind of exposure,” avRutick says.

Folbot competes against such household names as L.L. Bean and Cabela's—there's no way the smaller company could challenge the larger ones without widespread interactive communication. However, critics point out that social media sites vary widely in their value to small businesses. “The hype right now exceeds the reality,” observes Larry Chiagouris, a professor of marketing at Pace University's Lubin School of Business.

Despite the fact that the use of social media by firms with fewer than 100 employees doubled in one recent year, only 22 percent of those who responded to a separate survey reported a direct increase in profits as a result of social media use, while half said they broke even on the investment. Others caution that social media networking eats up valuable time, particularly for entrepreneurs whose day is chock-full of tasks ranging from design to distribution and manufacturing to marketing.

Most entrepreneurs support the use of social media, but with moderation. Chris Lindland, owner of Cordarounds.com, an online clothing retailer, advises patience. “My business has been visited millions of times, but I haven't made millions of sales,” he comments. But he believes patience pays off.

Questions for Critical Thinking

How will social networking change the business environment for entrepreneurs?

How might entrepreneurs use social media to secure financing?

Assess the Impact of Globalisation

1. What are the advantages and disadvantages of each?

Globalization has many advantages and disadvantages to each type of globalization that exists. The most common when globalization is being discussed is economic globalization, which deals with the impact of globalization on countries economy. One advantage to economic globalization is increased competition. Increased competition is great for countries especially those that are newer to the global economy as it helps them to identify themselves in the economy and encourages aggressive growth. A second important advantage is the spread of technology and innovation that businesses are able to share with one another. This is a crucial component to the global economy as technology enables economies to be global in the first place. Without the correct infrastructure, technology and innovation, it is impossible for a country to remain connected to the global economy and other countries. A third advantage to economic globalization is the development of higher standards of living for society in countries that are on the rise for globalization. An example of this would be India where their economy has really taken off in the last 10-15 years. India has really made a mark in the global economy in the information technology sector. As a result, India has become a key player in the global economy, which has significantly helped improve their workforce, society, and products/services that it offers. One disadvantage that economic globalization offers is the contribution to cultural homogeneity or creating a monoculture. The thought is that if countries continue to adapt the same trends and global ideologies, there will be a loss of culture and identity for countries. While having similar views across the world can be a uniting function across different cultures, it can also contribute to the creation of a monoculture; which means less of a unique identity for countries in the global space. A second disadvantage of economic globalization is that large corporations gain more power. Think about a really large company like Google where they are in more than 50 countries throughout the world. Moreover, it’s parent company, Alphabet, is in more than 70 countries throughout the world.

Provide a 300 word response

Consider the following scenario. Carole is an animal-rights activist who owns a sanctuary called Large Cat Rescue, while Joe owns a zoo called Tiger Kingdom. There is an ongoing feud between them with Carole alleging abuse of animals in Tiger Kingdom while Joe counteracts with similar accusations about Large Cat Rescue. In a recent escalation of this feud, Carole sues Joe for making defamatory comments about her personal life on a social media forum called Rumorville. Five weeks from now a judge will decide whether or not Joe is guilty. If found guilty Joe will be ordered to pay $4 million in damages to Carole; if not, there will be no payment. However, Carole and Joe can settle out of court in the four weeks prior to the hearing, in which case they do not go to court in Week 5. The negotiation for settlement proceeds as follows. In each week ?? ∈ {1, 2,3, 4} Carole or Joe can make a settlement offer St and the other party has to decide whether to accept it. Carole and Joe take turns making offers; Carole makes offers in weeks 1 and 3, while Joe gets his turn in weeks 2 and 4. If the offer is accepted in any particular week, the game ends and Joe pays St (the amount decided in week t) to Carole. Carole is risk-averse and her utility from receiving payment x is (x)1/2. She does not discount future payoffs and does not incur any costs of negotiation for going to court. Joe, however, is riskneutral and needs to pay a small fee c > 0 to lawyers for every week the negotiations take place. Use backward induction to analyse the above scenario. For the purpose of your analysis you may assume a probability p=0.7 of Carole winning the court case if the negotiations are not settled.

=============================================================================

can someone explain to me what is going in in this loop i am so lost...The only thing i understand is the count++;

The part im having trouble understanding is why:

i < l1 - l2 +1   and also   strstr(str + i, searchString) == str + i (like why the '+ i')      and also why    i = i + l2 -1;

for(int i = 0; i < l1 - l2 +1; i++)
{
if(strstr(str + i, searchString) == str + i)
{
count++;
i = i + l2 -1;
}
