Dog Up! Franks is looking at a new sausage system with an installed cost of $343,200. This cost will be depreciated straight-line to zero over the project's 7-year life, at the end of which the sausage system can be scrapped for $52,800.

If the tax rate is 21 percent and the discount rate is 11 percent, what is the NPV of this project?
