Creekside Campground is considering adding a driving range to its facility. The range would cost $48,000, would be depreciated on a straight line basis over its 6-year life, and would have a zero salvage value. The anticipated income from the project is $26,000 a year with $9,800 of that amount being variable cost. The fixed cost would be $7,400. The firm believes that it will earn an additional $7,500 a year from its current operations should the driving range be added. The project will require $5,000 of net working capital, which is recoverable at the end of the project. What is the internal rate of return on this project at a tax rate of 35 percent?
