You are evaluating two different silicon wafer milling machines. The PPTechron I costs $$276,000,$ has a $3-$year life, and has pretax operating costs of $$75,000$ per year. The Techron II costs $$480,000,$ has a $5-$year life, and has pretax operating costs of $$48,000$ per year. For both milling machines, use straight$-$line depreciation to zero over the project$$s life and assume a salvage value of $$52,000.$ If your tax rate is $21$ percent and your discount rate is $12$ percent, compute the EAC for both machines
