Assume a cost improvement project has only a first cost of $100,000 and a monthly net savings, M. There is no salvage value. Graph the project's IRR for payback periods from 6 months to the project's life of N years. The firm accepts projects with a 2- year payback period or a 20% IRR. When are these standards consistent and when are they not? Assume that N = 3 years. Assume that N=5 years. Assume that N= 10 years. What recommendation do you have for the firm about its project acceptance criteria
