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.]

Prepare a contribution format income statement for last year. (Round per unit computations to 2 decimal places, e.g. 0.38.)   W Promotions sells T-shirts imprinted with high school names and logos. Last year the shirts sold for $20.00 each, and variable costs were $8.50 per shirt. At this cost structure, the breakeven point was 24,600 shirts.
