You are evaluating two different silicon wafer miling machines. The Techron I costs $222,000, has a three-year life, and has pretax operating costs of $57,000 per year. The Techron Il costs $390,000, has a five-year life, and has pretax operating costs of $30,000 per year. For both milling machines, use stralght-line depreciation to zero over the project's life and assume a salvage value of $34,000. If your tax rate is 21 percent and your discount rate is 9 percent, compute the EAC for both machines. (Your answer should be a negative value and indicated by a minus sign. Do not round Intermediate calculations and round your answers to 2 decimal places, e.g., 32.16.) Techroni Techron 11 $ -88,773.31 Which machine should you choose? Techron 11 Techron Prev 5 of 10 24
