Can someone show me how to do this on the calculator? I'm getting confused on how to plug im the operating cash flows and the after tax salvage value

You are evaluating two different silicon wafer milling machines. The Techron I costs $219,000, has a three-year life, and has pretax operating costs of $56,000 per year. The Techron Il costs $385,000, has a five-year life, and has pretax operating costs of $29,000 per year. For both milling machines, use straight-line depreciation to zero over the project's life and assume a salvage value of $33,000. If your tax rate is 34 percent and your discount rate is 8 percent, compute the EAC for both machines. (Your answers 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.)
