Straight-line DepreciationBook value is the value of an asset that a company uses to create its balance sheet.Some companies depreciate their assets using straight-line depreciation so that thevalue of the asset declines by a fixed amount each year. The amount of the declinedepends on the useful life that the company assigns to the asset. Suppose that acompany just purchased a fleet of new cars for its sales force at a cost of $31,500 percar. The company chooses to depreciate each vehicle using the straight-line methodover 7 years. This means that each car will depreciate by +31,500 7 = +4500 per year.(a) Write a linear function that expresses the book value V of each car as a functionof its age, x.(b) Graph the linear function.(c) What is the book value of each car after 3 years?(d) Interpret the slope.(e) When will the book value of each car be $9000?[Hint: Solve the equation V1x2 = 9000.]

Consider each of the after-tax cash flows shown in the table below. Suppose that projects B and C are mutually exclusive. Suppose also that the required service period is eight years and that the company is considering leasing comparable equipment with an annual lease expense of $3,000, payable at the end of each year for the remaining years of the required service period. Which project is a better choice at 15%? Click the icon to view the cash flows for the projects. Click the icon to view the interest factors for discrete compounding when i=15% per year. The present worth of project B is $thousand. (Round to one decimal place.)
