Collect Customer Data - Part 2

1. Collect Mileage information:

   Prompt: "Starting Odometer Reading:\n"

   Variable: odoStart = ?

   Prompt: "Ending Odometer Reading:\n"

   Variable: odoEnd = ?

   Add code to PRINT odoStart and odoEnd variables as well as the totalMiles to check your work.

   The following data will be used as input in the test:

   1. Prompt the user to input the starting odometer reading (expect type int from the user)
   2. Prompt the user to input the ending odometer reading (expect type int from the user)
   3. Test your code.

Many lakes in the Adirondack State Park in New York are carefully managed. At some lakes, fines are levied for introducing non-intended fish into the lake. Why would such a rule exist? (Answer this question from an externality perspective!)

Many hotels have implemented aggressive recycling programs. Assume an employee within the hotel approached you about starting a comprehensive recycling program. What factors would influence the hotel’s decision to make a commitment to such a program?

Explain what is meant by the Theme Park internal and external business environment and use the acronym P.E.S.T with appropriate examples to clarify your explanation.  Also, discuss using how new rides can be both interactive and educational.

Beta and required rate of return

A stock has a required return of 12%; the risk-free rate is 2.5%; and the market risk premium is 3%.

What is the stock's beta? Round your answer to two decimal places.

B. If the market risk premium increased to 9%, what would happen to the stock's required rate of return? Assume that the risk-free rate and the beta remain unchanged.

1. If the stock's beta is equal to 1.0, then the change in required rate of return will be greater than the change in the market risk premium.

2. If the stock's beta is equal to 1.0, then the change in required rate of return will be less than the change in the market risk premium.

3. If the stock's beta is greater than 1.0, then the change in required rate of return will be greater than the change in the market risk premium.

4. If the stock's beta is less than 1.0, then the change in required rate of return will be greater than the change in the market risk premium.

5. If the stock's beta is greater than 1.0, then the change in required rate of return will be less than the change in the market risk premium.
