For the opening night at the Opera House, a total of 1000 tickets
were sold. Front orchestra seats cost $90 apiece, rear orchestra
seats cost $70 apiece, and front balcony seats cost $50 apiece. The
combined number of tickets sold for the front orchestra and rear
orchestra exceeded twice the number of front balcony tickets sold
by 400. The total receipts for the performance were $70,800.
Determine how many tickets of each type were sold.

Joan and Rick spent 3 weeks (21 nights) touring four cities on the
East Coast—Boston, New York, Philadelphia, and Washington. They
paid $220, $440, $180, and $200 per day for lodging in each city,
respectively, and their total hotel bill came to $6,360. The number
of days they spent in New York was the same as the total number of
days they spent in Boston and Washington, and the couple spent 3
times as many days in New York as they did in Philadelphia. How
many days did Joan and Rick stay in each city?
| Boston | days |

I just started this job 2 weeks ago as the CEO’s personal assistant. He is married 3x and is a very charismatic man, the CEO of a self-built multi-million empire. After a few days, he suddenly asked me if he could take me out to diner in London, if I book my flights and hotel he will afterwards reimburse me. [1] It was then, she relates, that she knew he wanted to sleep with her. In her words, she’s “totally not interested, but wants to preserve the job by not rejecting him.” So she made an excuse to get out of it and her post continues: “He then bothered me for hours about giving him good reasons why I couldn’t go. Then he said OK, next week we will go to Milan! He is a very powerful man, and I just get nervous of him. But I really do not want to lose my job. What should I do?” [
2] Make the case that Chourok C is not ethically free to go to Milan with him in order to advance her career, regardless of whether she’s attracted to him or not. The poster called Skater Boi proposes an aggressive solution: “Get a voice recorder and record what he says: blackmail if he tries to fire you.”

Suppose that you are responsible for making arrangements for a business convention and that you have been charged with choosing a city for the convention that has the least expensive rooms. You have narrowed your choices to Atlanta and Houston. The table containing samples of prices for rooms in Atlanta and Houston is provided in the Excel Online file below. Construct a spreadsheet to answer the following questions. Because considerable historical data on the prices of rooms in both cities are available, the population standard deviations for the prices can be assumed to be $19.88 in Atlanta and $27.2 in Houston.

An important part of employee compensation is a benefits package, which might include health insurance, life insurance, child care, vacation days, retirement plan, parental leave, bonuses, etc. Suppose you want to conduct a survey of benefits packages available in private businesses in Hawaii. You want a sample size of 100.
Some sampling techniques are described below. Categorize each technique as simple random sample, stratified sample, systematic sample, cluster sample, or convenience sample. Put your answer in the blank.
a. Assign each business in the Island Business Directory a number, and then use a random number table to select the businesses to be included in the sample. __________________________
b. Use postal ZIP Codes to divide the state into regions. Pick a random sample of 10 ZIP Code areas and then include all the businesses in each selected ZIP Code area. ________________________
c. Send a team of five research assistants to Bishop Street in downtown Honolulu. Let each assistant select a block or building and interview an employee from each business found. Each researcher can have the rest of the day off after getting responses from 20 different businesses. _____________________
d. Use the Island Business Directory. Number all the businesses. Select a starting place at random, and then use every 50th business listed until you have 100 businesses. _____________________
e. Group the businesses according to type: medical, shipping,
retail, manufacturing, financial, construction, restaurant, hotel,
tourism, other. Then select a random sample of businesses from each
business type. ____________________

TEXplor has purchased a 2-year lease on land adjacent
to the land leased by
Clampett. The land leased by TEXplor lies above the same crude oil
deposit. Assume
Management of AG Travel and Tour has identified two groups of
individuals that
would be interested in the vacation package consisting of room and
board and/or
entertainment. The maximum amount that group 1 is willing to pay
for room and
board is GHC 2500 and for entertainment is GHC 500. For group 2,
the maximum
amount they are willing to pay for room and board is GHC 1800 and
for
entertainment is GHC 750. Although AG Travel and Tour is not able
to identify
members of either group, it does know that each group values the
components of
the package differently. Assuming there are an equal number of
members in each
group and that the total membership in each group is a single
individual. If the
marginal cost of providing the service (room and board and/or
entertainment) to
each group is GHC 1000.
i. How much will the hotel charge members of each group for the
vacation
package if it could identify the members in each group?
ii. How much will the profit for AG Travel and Tour be?
iii. Since AG Travel and Tour is not able to identify members of
each group,
what price should it charge for each product?
iv. What will be the profit for AG Travel and Tour in the case of
(iii) above?
v. If AG Travel and Tour wants to charge a package price, what is
the highest
price it can charge?
vi. What profit will AG Travel and Tour make if it charges the
package price
found in (v) above? (3 mark

Question 1: [5 Points]
For each of the following systems, choose a suitable architecture style, then justify your choice.
In: Computer Science
In this assignment, you will be selecting a product of interest and you will build a sales strategy to improve the sales performance for that product. A product is only one of the four pillars of a marketing strategy, and so you will need to build a thorough understanding of how the price of this product is set, what channels are available for the physical housing and distribution of the product, and how this product will be promoted (commonly referred to as the four “P”s of marketing: Product, Price, Place and Promotion). This will be the main body of your research, and you will draw on all of these as you perform your analyses and draft your strategy.
You will be given the following scenario: Suppose you are leading a sales team tasked with either building a new market for your product in the location you choose, or for capturing existing market share for that product. The locations and the nuances of your product will largely fall on you as you make your choice, but you will want to keep in mind that the research you are doing will involve the dynamics of the industry, key players and competition, competitive intensity or barriers to entry, the legal environment, as well as geographic constraints. The location is largely up to you: We live in the great State of Maine, so you’re free to build a strategy that you can deploy locally, or you can choose a different state or country if you wish. The only real constraint is you will want to ensure that the product and place you select will make sense conceptually. It would likely be a doomed strategy to market a water-park deep in the Sahara Desert.

Plastics, Inc. and Joe's Canoe Shack both operate businesses located on the river. Plastics, Inc. dumps pollution into the river, which results in fewer canoe rentals for Joe. The marginal cost of cleaning up the pollution is $20,000 for Plastics, Inc. Joe estimates a reduction in pollution will lead to a marginal benefit of $13,000.
a. If Joe owns the rights to the river, which of the following is the most likely outcome?
Below is a set of projects aimed at cleaning up a city's recreational areas. Determine whether the city should undertake the cleanup effort. Assume the city has enough money in its budget to undertake all projects.

| North Park | $12,000 | $15,000 | (Click to select) Yes No |
| Upper River Beach | 7,000 | 4,000 | (Click to select) Yes No |
