Consider the following two mutually exclusive projects being considered by an agency. The agency's MARR is 3% per year and the projects have a service life of 5 years. Answer the following questions. a. Based on the PW, the project that is more economical is Project 2 (Enter the project number). b. Calculate the IRR of each alternative (use the trial-and-error method) The IRR of Project 1 is \% (Round to the nearest one decimal place) The IRR of Project 2 is 8% (Round to the nearest one decimal place) c. Perform the incremental IRR analysis to determine the project that is more economical: Incremental IRR = 5% (Round to the nearest one decimal place); Therefore, based on the incremental IRR, Project is more economical. d. Do the two methods produce the same recomendation for the most economical project? A. Yes B. No e. IMPORTANT: Note from this example that a higher IRR for an individual alternative does not guarantee that the alternative is more economical than the one with a lower IRR. It is the incremental IRR value relative to the MARR
