Dog Up$!$ Franks is looking at a new sausage system with an installed cost of $$660,431.$ This cost will be depreciated straight$-$line to $67,874$ over the project's $7-$year life, at the end of which the sausage system can be scrapped for $$113,385.$ The sausage system will save the firm $$252,746$ per year in pretax operating costs, and the system requires an initial investment in net working capital of $$45,163.$ If the tax rate is $0\mathrm{.}26$ and the discount rate is $0\mathrm{.}09,$ what is the total cash flow in year $7?($Make sure you enter the number with the appropriate $+/-$ sign$)$
