Market Top Investors, Incorporated, is considering the purchase of a $$465,000$ computer with an economic life of six years. The computer will be fully depreciated over six years using the straight$-$line method, at which time it will be worth $$126,000.$ The computer will replace two office employees whose combined annual salaries are $$97,000.$ The machine will also immediately lower the firm$$s required net working capital by $$86,000.$ This amount of net working capital will need to be replaced once the machine is sold. The corporate tax rate is $21$ percent. The appropriate discount rate is $11$ percent. Calculate the NPV of this project.
