Plz help with this problem, I'll rate :) !!!!

Cullumber Corp. is thinking about opening a soccer camp in southern California. To start the camp, Cullumber would need to purchase land and build four soccer fields and a sleeping and dining facility to house 150 soccer players. Each year, the camp would be run for 8 sessions of 1 week each. The company would hire college soccer players as coaches. The camp attendees would be male and female soccer players ages 12-18. Property values in southern California have enjoyed a steady increase in value. It is expected that after using the facility for 20 years, Cullumber can sell the property for more than it was originally purchased for. The following amounts have been estimated. Assume that during the first 5 years, the annual net cash flows each year were only $40,120. At the end of the fifth year, the company is running low on cash, so management decides to sell the property for $1,335,996. What was the actual internal rate of return on the project? (Round answer to 0 decimal places, e.g. 13\%. For calculation purposes, use 5 decimal places as displayed in the factor table provided.)
