Please show/explain work. Scott Investors, Inc, is considering the purchase of a 412,000 computer with an economic life of 5 years. The computer will be fully depreciated over five years using the straight-line method. The market value of the computer will be 76,000 in five years. The computer will replace 5 office employees whose combined income annual salaries are 121,000. The machine will also immediately lower the firm's required net working capital by 96,000. This amount of networking capital will need to be replaced once the machine is sold. The corporate tax is 34 percent. The appropriate discount rate is 15%. Calculate the NPV on this project.
