Market Top Investors, Inc., is considering the purchase of a $365,000 computer with an economic life of four years. The computer will be fully depreciated over four years using the straight-line method, at which time it will be worth $114,000. The computer will replace two office employees whose combined annual salaries are $95,000. The machine will also immediately lower the firms required net working capital by $84,000. This amount of net working capital will need to be replaced once the machine is sold. The corporate tax rate is 24 percent. The appropriate discount rate is 9 percent.
