A well-known financial writer argues that he can earn 101 percent per year buying wine by the case. Specifically, he assumes that he will consume one $10 bottle of fine Bordeaux per week for the next 12 weeks. He can either pay $10 per week or buy a case of 12 bottles today. If he buys the case, he receives a 7 percent discount and, by doing so, earns the 101 percent. Assume he buys the wine and consumes the first bottle today. Calculate the EAR. (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e. g., 32.16.)
