You are evaluating two different silicon wafer milling machines. The Techron I cost $270,000, has a 3-year life, and has pretax operating costs of $73,000 per year. The Techron II costs $470,000, has a 5-year life, and has pretax operating costs of $46,000 per year. For both milling machines, use straight-line depreciation to zero over the projects life and assume a salvage value of $50,000. If your tax rate is 24 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.)

Which machine do you prefer?

• Techron I
• Techron II
