Market Top Investors, Incorporated, is considering the purchase of a $425,000 computer with an economic life of five years. The computer will be fully depreciated over five years using the straight-line method, at which time it will be worth $35,000. The computer will replace two office employees whose combined annual salaries are $95,000. The machine also will immediately lower the firms required net working capital by $40,000. This amount of net working capital will need to be replaced once the machine is sold. The corporate tax rate is 22 percent. The appropriate discount rate is 9 percent.
