Internal Rate of Return Method for a Service Company

The Riverton Company, a Utah ski resort, recently announced a $215,352 expansion of lodging properties, lifts, and terrain. Assume that this investment is estimated to produce $72,000 in equal annual cash flows for each of the first five years of the project life.
