Suppose you’re evaluating three alternative MMMF investments. The first fund buys a diversified portfolio of municipal securities from across the country and yields 4.2 percent. The second fund buys only taxable, short-term commercial paper and yields 5.9 percent. The third fund specializes in the municipal debt from the state of New Jersey and yields 3.7 percent. If you are a New Jersey resident, your federal tax bracket is 38 percent, and your state tax bracket is 7 percent.
Calculate the sum of after-tax percentage yield of the three alternatives. (Round your answer to 2 decimal places. Omit the "%" sign in your response.)
