Charlie has a project for which he had determined a present worth of $56 740. He now has to calculate the IRR for the project, but unfortunately he has lost complete information about the cash flows. He knows only that the project has a five-year service life and a first cost of $180 000, that a set of equal cash flows occurred at the end of each year, and that the MARR used was 10 percent. What is the IRR for this project?
