On March 1, 2013, Brandy paid 400 Mexican pesos for a manicure in Playa del Carmen, Mexico. Because she only had
Japanese yen, she needed to exchange her Japanese yen at a nearby money-exchange kiosk in order to get the 400 Mexican
pesos she used to pay the manicurist. The kiosk is able to buy and sell U.S. dollars, Mexican pesos, and Japanese yen at the
exchange rates shown in the table. Approximately how much did the manicure cost Brandy in terms of Japanese yen?
