You are evaluating two different silicon wafer milling machines. The Techron I costs $245,000, has a three-year life, and has pretax operating costs of $63,000 per year. The Techron Il costs $420,000, has a five-year life, and has pretax operating costs of $35,000 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 22 percent and your discount rate is 10 percent, compute the EAC for both machines. (A negative answer should be indicated by a minus sign. Do not round intermediate calculations and round your answers to 2 decimal places, e.g.,32.16.) Techron I Techron lI Which do you prefer? Techron Techron Il
