An investor in the United States bought a one-year Brazilian security valued at 330,000 Brazilian reals (R$). The U.S. dollar equivalent was $280,000. The Brazilian security earned 16 percent during the year, but the Brazilian real depreciated 5 cents against the U.S. dollar during the time period ($0.85 to $0.80).

After transferring the funds back to the United States, what was the investors return on her $280,000? (Do not round intermediate calculations. Input your answer as a percent rounded to 2 decimal places.)
