You are evaluating two different silicon wafer milling machines. The Techron 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 projects 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.
