Ryan Lock had planned his trip to the Olympic Games in Rio de Janeiro, Brazil, for many months. He had budgeted-saved-$13,000 for expenses while in Rio. But he had postponed exchanging the dollars for Brazilian currency-real (BRL or R$)-until the very last minute on August 8th, doing it in the airport in the United States at BRL 2.8350 = 1.00 USD.
Given the following average monthly exchange rates in 2016, when should he have exchanged the dollars for real to maximize his Brazilian spending money?
