Dog Up! Franks is looking at a new sausage system with an installed cost of $385,000. 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 $60,000. The sausage system will save the firm $135,000 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 21 percent and the discount rate is 10 percent, what is the NPV of this project? (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.)
