You are evaluating two different silicon wafer milling machines. The Techron 1 costs $240,000, has a three-year life, and has pretax operating costs of $63,000 per year. The Techron II costs $420,000, 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 $40,000. If your tax rate is 35% and your discount rate is 10%, compute the EAC for both machines. Which do you prefer? Why?
