5) Cory is analyzing two mutually exclusive machines that will upgrade its manufacturing plant. These machines are considered average-risk projects, so management will evaluate them at the firm's 10% WACC. Machine X has a life of 4 years, while Machine Y has a life of 2 years. The cost of each machine is $60,000; however, Machine X provides after-tax cash flows of $25,000 per year for 4 years and Machine Y provides after-tax cash flows of $42,000 per year for 2 years. The manufacturing plant is very successful, so the machines will be repurchased at the end of each machine's useful life. a) Using the replacement chain approach, what is the NPV of the better machine? b) Using the EAA approach, what is the EAA of the better machine
