1 You are evaluating two different silicon wafer milling machines. The Techron | costs $291,000, has a 3-year life, and has pretax operating costs of $80,000 per year. The Techron Il costs $505,000, has a 5-year life, and has pretax operating costs of $47,000 per year. For both milling machines, use straight-line depreciation to zero over the project's life and assume a salvage value of $57,000. If your tax rate is 21 percent and your discount rate is 13 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.) 33.33 points eBook Techron | References Techron II Which machine do you prefer? Techron 11 O Techron
