You are evaluating two different milling machines. Machine I costs $270,000, has a three-year life, and has pre-tax operating costs of $70,000 per year. Machine II costs $475,000, has a four-year life, and has pre-tax operating costs of $36,000 per year. Both machines have a CCA rate of 20% per year. Assume a salvage value of $45,000 for each machine. The tax rate is 30% and the discount rate is 10%. Required: Compute the equivalent annual cost (EAC) for each machine and compare costs. Which machine do you prefer and why? Round your EAC answers to 2 decimal places. Show your calculator keystrokes and solutions for the NPV of Machine I and Machine II based on the above information. Show your calculator keystrokes and solutions for computing the annual PMT for each machine based on the above information. (16 marks)
