You are considering an investment opportunity that requires an initial investment of $150 million in period 0. The project will generate only one future payment of $184 million at the end of the second year. The cost of capital is 8%. 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.]
