The Sausage Hut is looking at a new sausage system with an installed cost of $438,000. This cost will be depreciated straight-line to zero over the project's four-year life, at the end of which the sausage system can be scrapped for $69,000. The sausage system will save the firm $129,000 per year in pretax operating costs, and the system requires an initial investment in net working capital of $29,000, which will be recouped at project end. If the tax rate is 35 percent and the discount rate is 6 percent, what is the NPV of this project? O $8.620 O-$18.870 O $7.580 O $14,845 O $29.80
