Question 4 (12 points) Rory Laundromat is looking at a new commercial dryer system with an installed cost of $400,000. This cost will be depreciated straight-line to zero over the system's 5-year life, and at the end of which the system can be scrapped for $68,000. The project will save the firm $120,000 per year in pretax operating costs, and it requires an initial investment in net working capital of $35,000. If the tax rate is 25% and the discount rate is 10%, what is the NPV of this project
