20. The Sausage Hut is looking at a new sausage system with an installed cost of $187,400. 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 $25,000. The sausage system will save the firm $69,000 per year in pretax operating costs, and the system requires an initial investment in net working capital of $9,000, which will be recouped at project end. If the tax rate is 34 percent and the discount rate is 12 percent, what is the NPV of this project? A. $6,508.54 B. -$320.81 C. $560.24 D. $1,410.10 E. $8,211.15
