You are evaluating two different silicon wafer milling machines. The Techron I costs $270,000, has a three-year life, and has pretax operating costs of $73,000 per year. The Techron II costs $470,000, has a five-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 25 percent and your discount rate is 9 percent, compute the EAC for both machines.

The Techron Il costs $470,000, has a five-year life, and has pretax operating costs of $46,000 per year. For both milling machines, use straight-line depreciation to zero over the project's life and assume a salvage value of $50,000. If your tax rate is 25 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.) Techron 1 Techron 11 Which machine should you choose? Techron II Techron
