The Campbell Company is considering adding a robotic paint sprayer to its production line. The sprayer's base price is $$1,000,000,$ and it would cost another $$20,000$ to install it$.$ The machine falls into the MACRS $3-$year class, and it would be sold after $3$ years for $$592,000.$ The MACRS rates for the first three years are $0\mathrm{.}3333,0\mathrm{.}4445,$ and $0\mathrm{.}1481.$ The machine would require an increase in net working capital $($inventory$)$ of $$13,500.$ The sprayer would not change revenues, but it is expected to save the firm $$399,000$ per year in before$-$tax operating costs, mainly labor.

Campbell's marginal tax rate is $25\%.($Ignore the half$-$year convention for the straight$-$line method.$)$ Cash outflows, if any, should be indicated by a minus sign. Do not round intermediate calculations. Round your answers to the nearest dollar.
