Your buddy is in a bind and needs to sell his fishing boat. You've got some extra cash, so you buy it from him for $2800 and park it in the yard. Exactly one year later, a guy stops and offers you $3100 for the boat and you take him up on it. Compute the internal rate of return on your investment in percent. Round your answer to the nearest 0.1%. (Do multiply by 100 but do not enter the % symbol.)
