The variable costing concept removes fixed costs, which are uncontrollable, from the decision-making process (see variable costing income statement). This forces management to focus on the variable factors of production, sales revenue and variable costs. I remember learning this concept in economics at LBCC, where a company should shut down if a product’s price falls below variable cost and just incur fixed costs.

Have you ever heard the saying “The company loses $1.00 on every unit sold, but we are confident the losses can be made up on volume.” Really?

In theory, companies should not operate with a negative contribution margin (sales revenue-variable costs), but my guess is that some do especially in this economic environment?

Do you think companies actually operate (or produce products) with a negative contribution margin?

Identify and list each of Poter's five forces that determine competition and the industrial profitability of the market eg rivals, barriers to entry, suppliers, substitutes, and buyers. You may want to do this using a visual aid, like a chart. Pick any organization you are familiar with and describe its overall competitive environment using each of the forces. Analyze how each of The Five Forces affects the organization and how each force may affect the ones. Evaluate which force is the strongest and why. Which is the weakest?

Assume you invented a new plastic-shaping technology that allows plastic products to be manufactured much more cheaply. When you talk to manufacturers, though, they are skeptical because the new method is so radically different from any technology they have ever used before. What do you think the sales cycle for the technology would look like? What would the most important step of the sales cycle be? Why? What type of sales force would you utilize and why? What marketing activities could help you shorten the sales cycle and how?

Submit description of resilience as pertains to natural disasters. Answer the following questions in your synthesis:

What is the definition of resilience as pertains to natural disasters?

Do different organizations or disciplines use different definitions? If so, analyze the different definitions, and compare and contrast the concepts that are included therein.

Select the definition that you will use in your final project, and make an argument for why this is the most relevant definition for your paper.

Fantastic Styling Salon is run by three stylists, Jenny​ Perez, Jill​ Sloan, and Jerry​ Tiller, each capable of serving five customers per​ hour, on average. Use POM for Windows or OM Explorer to answer the following questions:

Note: During busy periods of the​ day, when nine customers on average arrive per​ hour, all three stylists are on staff.

a. If all customers wait in a common line for the next available​ stylist, how long would a customer wait in​ line, on ​average, before being​ served?

b. Suppose that each customer wants to be served by a specific​stylist, 1/3 want​ Perez, 1/3 want​ Sloan, 1/3 want Tiller. How long would a customer wait in​ line, on​ average, before being​served?

c. If all customers wait in a common line for the next available​ stylist, how long would a customer wait in​ line, on​average, before being​ served?

d. Suppose that each customer wants to be served by a specific​stylist, 60​% want Perez and 40​% want Sloan. How long would a customer wait in​ line, on​ average, before being served by​ Perez? By​ Sloan? Overall?

I would really appreciate it if all work is shown! Thank you for your time.

Assume that you are working for the Ministry of Health in the geriatric department. The department is planning to create a specific geriatric care model for older adults to meet their needs and enable them to be healthy while they are aging. Your supervisor asks you to address one of the common geriatric syndromes to be used in that model.

1. What is the geriatric syndrome that you are going to address?

2. Explain your approach/policy that you will use to help prevent/reduce the health issue? Explain it thoroughly.

3. Why do you think your approach is appropriate for that issue?

A local biologist needs a program to predict population growth. The inputs would be:

1. The initial number of organisms, as an int
2. The rate of growth (a real number greater than 1), as a float
3. The number of hours it takes to achieve this rate, as an int
4. A number of hours during which the population grows, as an int

For example, one might start with a population of 500 organisms, a growth rate of 2, and a growth period to achieve this rate of 6 hours. Assuming that none of the organisms die, this would imply that this population would double in size every 6 hours. Thus, after allowing 6 hours for growth, we would have 1000 organisms, and after 12 hours, we would have 2000 organisms.

Write a program that takes these inputs and displays a prediction of the total population.

An example of the program input and output is shown below:

Enter the initial number of organisms: 10
Enter the rate of growth [a real number > 1]: 2
Enter the number of hours to achieve the rate of growth: 2
Enter the total hours of growth: 6

The total population is 80

also make sure it test for these cases

Test Case 1

Test for 100 organisms with growth rate of 5 over 2 hrs over 25 hrs total

Test Case 2

Test for 10 organisms with growth rate of 2 over 2 hrs over 6 hrs total

Test Case 3

Test for 0 organisms with growth rate of 5 over 1 hr over 6 hrs total

Test Case 4

Test for 7 organisms with growth rate of 7 over 7 hrs over 7 hrs total
