You are evaluating two different silicon wafer milling machines. The Techron I costs $$258,000,$ has a three$-$year life, and has pretax operating costs of $$69,000$ per year. The Techron II costs $$450,000,$ has a five$-$year life, and has pretax operating costs of $$42,000$ per year. For both milling machines, use straight$-$line depreciation to zero over the project$$s life and assume a salvage value of $$46,000.$ If your tax rate is $25$ percent and your discount rate is $10$ percent, compute the EAC for both machines.
