Symon Meats is looking at a new sausage system with an installed cost of $455,000. This cost will be depreciated straight-line to zero over the projects five-year life, at the end of which the sausage system can be scrapped for $65,000. The sausage system will save the firm $235,000 per year in pretax operating costs, and the system requires an initial investment in net working capital of $24,000. If the tax rate is 34 percent and the discount rate is 10 percent, what is the NPV of this project?
