Joan has proposed upgrading the inkjet printers in the marketing department with color laser printers. The purpose of the change is to reduce the cost per page printed because toner is less expensive than ink and the duty cycle of laser printers is longer than that of inkjet printers. The marketing department currently has three inkjet printers. What's her logical next step?

You are evaluating two different silicon wafer milling machines. the techron i costs $285,000, has a three-year life, and has pretax operating costs of $78,000 per year. the techron ii costs $495,000, has a five-year life, and has pretax operating costs of $45,000 per year. for both milling machines, use straight-line depreciation to zero over the project’s life and assume a salvage value of $55,000. if your tax rate is 24 percent and your discount rate is 11 percent, compute the eac for both machines.
