Kolby's Korndogs is looking at a new sausage system with an installed cost of $800,000. 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 $95,000. The sausage system will save the firm $150,000 per year in pretax operating costs, and the system requires an initial investment in net working capital of $45,000. If the tax rate is 35 percent and the discount rate is 10 percent, what is the NPV of this project? $321,957.41 -$421,957.56 $250,957.52 -$221,957.48
