You are evaluating two different silicon wafer milling machines. the techron i costs $261,000, has a three-year life, and has pretax operating costs of $70,000 per year. the techron ii costs $455,000, has a five-year life, and has pretax operating costs of $43,000 per year. for both milling machines, use straight-line depreciation to zero over the project�s life and assume a salvage value of $47,000. if your tax rate is 35 percent and your discount rate is 9 percent, compute the eac for both machines.
