An investor in the United States bought a one-year Brazilian security valued at 310,000 Brazilian reals (R$). The U.S. dollar equivalent was $260,000. The Brazilian security earned 15 percent during the year, but the Brazilian real depreciated 5 cents against the U.S. dollar during the time period ($.84 to $.79).

After transferring the funds back to the United States, what was the investors return on her $260,000? (Do not round intermediate calculations. Input your answer as a percent rounded to 2 decimal places.)
