[The following information applies to the questions displayed below.]

Three different companies each purchased trucks on January 1, Year 1, for $50,000. Each truck was expected to last four years or 200,000 miles. Salvage value was estimated to be $5,000. All three trucks were driven 66,000 miles in Year 1, 42,000 miles in Year 2, 40,000 miles in Year 3, and 60,000 miles in Year 4. Each of the three companies earned $40,000 of cash revenue during each of the four years. Company A uses straight-line depreciation, company B uses double-declining-balance depreciation, and company C uses units-of-production depreciation.

Answer each of the following questions. Ignore the effects of income taxes.

b-1. Calculate the net income for Year 4.
b-2. Which company will report the lowest amount of net income for Year 4?

Which company will report the lowest amount of net income for year 4?

We will make some changes to our first program. If you recall we began with, A car's gas mileage or miles-per-gallon (MPG) can be calculated with the following Formula: MPG = Miles Driven / Gallons of gas used. Write a class called Mileage. The Mileage class should have two private member variables called miles and gallons of type double. The class should have four public methods: setMiles and setGallons should use void return types; getMiles and getGallons should use double return types. It should have one more method called getMPG that performs the math calculation and returns the double MPG Write a program called MPGMain that asks the user for the number of miles driven and the gallons of gas used. It should call the Mileage class to calculate the car's MPG. The class should return the MPG to the MPGMain where it was called and display the value on the screen. (Format the display and limit the miles-per-gallon to 2 decimal places) in JAVA programming language

Amy Lloyd is interested in leasing a new Honda and has contacted three automobile dealers for pricing information. Each dealer offered Amy a closed-end 36-month lease with no down payment due at the time of signing. Each lease includes a monthly charge and a mileage allowance. Additional miles receive a surcharge on a per-mile basis. The monthly lease cost, the mileage allowance, and the cost for additional miles follow:

Dealer Monthly Cost Mileage Allowance Cost per Additional Mile
Hepburn Honda $299 36,000 $0.15
Midtown Motors $310 45,000 $0.20
Hopkins Automotive $325 54,000 $0.15

Amy decided to choose the lease option that will minimize her total 36-month cost. The difficulty is that Amy is not sure how many miles she will drive over the next three years. For purposes of this decision, she believes it is reasonable to assume that she will drive 12,000 miles per year, 15,000 miles per year, or 18,000 miles per year. With this assumption Amy estimated her total costs for the three lease options. For example, she figures that the Hepburn Honda lease will cost her 36($299) + $0.15(36,000 - 36,000) = $10,764 if she drives 12,000 miles per year, 36($299) + $0.15(45,000 - 36,000) = $12,114 if she drives 15,000 miles per year, or 36($299) + $0.15(54,000 - 36,000) = $13,464 if she drives 18,000 miles per year.

(a) What is the decision, and what is the chance event? Choose the correct answer below.
(i) The decision is to select the number of miles Amy will drive and the chance event is the three alternatives (Hepburn Honda, Midtown Motors, and Hopkins Automotive).
(ii) The decision is to select the monthly cost and the chance event is the three alternatives (Hepburn Honda, Midtown Motors, and Hopkins Automotive).
(iii) The decision is to select the best lease option from three alternatives (Hepburn Honda, Midtown Motors, and Hopkins Automotive) and the chance event is the number of miles Amy will drive.
(iv) The decision is to select the best lease option from three alternatives (Hepburn Honda, Midtown Motors, and Hopkins Automotive) and the chance event is the monthly cost that Amy will incur.
- Select your answer Option (iii)
(b) Construct a payoff table for Amy's problem.
Actual Miles Driven Annually
Dealer 12,000 15,000 18,000
Hepburn Honda $ $ $
Midtown Motors $ $ $
Hopkins Automotive $ $ $
(c) If Amy has no idea which of the three mileage assumptions is most appropriate, what is the recommended decision (leasing option) using the optimistic, conservative, and minimax regret approaches?
Optimistic approach Hepburn
Conservative approach Hopkins Automotive
Minimax approach Hopkins Automotive
(d) Suppose that the probabilities that Amy drives 12,000, 15,000, and 18,000 miles per year are 0.5, 0.4, and 0.1, respectively. What option should Amy choose using the expected value approach?
- Select your answer - Midtown Motors
(e) Develop a risk profile for the decision selected in part (d). What is the most likely cost?
$
What is its probability?
If required, round your answer to one decimal place.
