You are considering an investment opportunity that requires an initial investment of $159 million in period 0. Starting in one year, it will generate $12.1 million per year in perpetuity (i.e. every year forever). The cost of capital is 13%. What is the IRR (the internal rate of return) for the project? [Note that getting the actual value should not require trial and error or a financial calculator, because this is a simple case.] [Give your answer in percent, to one and only one decimal place, and with no percentage sign. For example, 6.2, 18.9 or 4.6. The software will mark it wrong otherwise, so please format your answer properly.]
