Project Evaluation. Kolby's Korndogs is looking at a new sausage system with an installed cost of $655,000. This cost will be depreciated straight-line to zero over the project's five-year life, at the end of which the sausage system can be scrapped for $85,000. The sausage system will save the firm $183,000 per year in pretax operating costs, and the system requires an initial investment in net working capital of $35,000. If the tax rate is 34 percent and the discount rate is 8 percent, what is the NPV of this project?
