lou are evaluating two different silicon wafer milling machines. The Techron I costs \$213,000, has a three-year life, and has pretax operating costs of $54,000 per year. The eechron II costs $375,000, has a five-year life, and has pretax operating costs of $27,000 per year. For both milling machines, use straight-line depreciation to zero over the project's life and assume a salvage value of $31,000. If your tax rate is 24 percent and our 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 :alculations and round your answers to 2 decimal places, e.g., 32.16.)
