5. You are evaluating two different silicon wafer milling machines. The Technotronic I costs $228,000, has a three-year life, and has pretax operating costs of $59,000 per year. The Technotronic II costs $400,000, has a five-year life, and has pretax operating costs of $32,000 per year. For both milling machines, use straight-line depreciation to zero over the project
