The Blue Sky Ski Resort plans to install a new chair lift. Construction is estimated to require an immediate outlay of $220,000. The life of the lift is estimated to be fifteen years with a salvage value of $75,000. Cost of clearing and grooming the new area is expected to be $20,000 for each of the first three years of operation. Net cash inflows from the lift are expected to be $39,000 for each of the first five years and $70,000 for each of the following ten years. Calculate the internal rate of return (IRR). The internal rate of return is %. (Round to the nearest tenth as needed.)
