You are evaluating two different silicon wafer milling machines. The Techron I costs $$300,000,$ has a $3-$year life, and has pretax operating costs of $$83,000$ per year. The Techron II costs $$520,000,$ has a $5-$year life, and has pretax operating costs of $$49,000$ per year. For both milling machines, use straight$-$line depreciation to zero over the project$$s life and assume a salvage value of $$60,000.$ If your tax rate is $24$ percent and your discount rate is $12$ percent, compute the EAC for both machines.
