Kinky Copies may buy a high$-$volume copier. The machine costs $$100,000$ and this cost can be fully depreciated immediately. Kinky anticipates that the machine actually can be sold in $5$ years for $$28,000.$ The machine will save $$18,000$ a year in $($after$-$tax$)$ labor costs but will require an increase in working capital, mainly paper supplies, of $$9,000.$ The firm$$s tax rate is $21\%,$ and the discount rate is $6\%.($Assume the net working capital will be recovered at the end of Year $5.)$
