You are evaluating two different silicon wafer milling machines. Machine I costs $120,000, has a 3-year life, and has pretax operating costs of $43,000 per year. Machine II costs $160,000, has a 5-year life, and has pretax operating costs of $20,000 per year. For both machines, use straight-line depreciation to zero over the project's life and assume a salvage value of $20,000. If your tax rate is 34 percent and your discount rate is 12 percent, which one do you...
