2. You are evaluating two different silicon wafer milling machines. The Techren I costs $270,000, has a three-year life, and has pretax operating costs of $69,000 per year. The Techten II costs $475,000, has a five-year life, and has pretax operating costs of $36,000 per year. For both milling machines, use straight-line depreciation to zero over the project's life and assume a salvage value of $45,000. If your tax rate is 35 percent and your discount rate is 10 percent, compute the EAC for both machines. Which do you prefer? Why
