Your firm is contemplating the purchase of a new $575,000 computer-based order entry system. The system will be depreciated straight-line to zero over its 5-year life. It will be worth $160,000 at the end of that time. You will save $176,000 before taxes per year in order processing costs, and you will be able to immediately reduce working capital by $80,000 (this is a one-time reduction at time zero). This amount of net working capital will need to be replaced once the order entry system is sold at the end of the fifth year. If the tax rate is 23% and the required return (or discount rate) is 14%,

a). What is the NPV of this project?

b). What is the IRR of this project?

c). Should your firm purchase the computer-based order entry system?

Please include formulatext in the answer. Thanks!
