Dog Up$!$ Franks is looking at a new sausage system with an installed cost of $$499,200.$ This cost will be depreciated straight$-$line to zero over the project's $4-$year life, at the end of which the sausage system can be scrapped for $$76,800.$ The sausage system will save the firm $$153,600$ per year in pretax operating costs, and the system requires an initial investment in net working capital of $$35,840.$

If the tax rate is $21$ percent, what do the annual cash flows look like for this project? Start with year $0,$ give me one number for years $1-3,$ and one for the end of year four when they sell the equiptment.
