Franks Franks is looking at a new sausage system with an installed cost of $397,800. 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 $61,200. The sausage system will save the firm $122,400 per year in pretax operating costs, and the system requires an initial investment in net working capital of $28,560. All of the net working capital will be recovered at the end of the project. The tax rate is 33 percent and the discount rate is 9 percent. What is the net present value of this project?
