Need answers to the 2nd and 3rd

Your firm is contemplating the purchase of a new $520,000 computer-based order entry system. The system will be depreciated straight-line to zero over its five-year life. It will be worth $56,000 at the end of that time. You will be able to reduce working capital by $81,000 (this is a one-time reduction). The tax rate is 22 percent and the required return on the project is 10 percent. If the pretax cost savings are $150,000 per year, what is the NPV of this project?
