Lou Construction is looking at a new system with an installed cost of $$411,500.$ This cost will be depreciated straight$-$line to zero over the project's seven$-$year life, at the end of which the system is expected to be sold for $$35,000$ cash. No bonus depreciation will be taken. The system will save the firm $$129,400$ per year in pretax operating costs, and the system requires an initial investment in net working capital of $$22,500.$ All of the net working capital will be recovered at the end of the project. The tax rate is $23$ percent and the discount rate is $13\mathrm{.}2$ percent. What is the net present value of this project?
