Dog Up$!$ Franks is looking at a new sausage system with an installed cost of $$491,400.$ This cost will be depreciated straight$-$line to zero over the project's $9-$year life, at the end of which the sausage system can be scrapped for $$75,600.$ The sausage system will save the firm $$151,200$ per year in pretax operating costs, and the system requires an initial investment in net working capital of $$35,280.$

If the tax rate is $21$ percent and the discount rate is $9$ percent, what is the NPV of this project?
