Imagine two scientists from another planet visit earth and attempt to study our computers. in his studies poz focuses on how the computer is used for conducting business, accessing research, communicating with others, and playing games, while zog concentrates on the construction of the hard drive, monitor, keyboard, and mouse. pozâs approach is most similar to while zogâs is most similar to â

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.
