1. Two college students went to Guadalajara, Mexico, on their spring breaks. One took the vacation in 2002, while the other went in 2006. Each student had $500 to spend. In 2002, the exchange rate of MXN/USD (Mexican pesos to U.S. dollars) was 9. In 2006, the exchange rate was 11. A hotel room in Guadalajara cost 200 pesos per night in 2002 and 220 pesos in 2006. If each student spent five nights in a hotel, which student had more pesos left over? Exactly how many did that student have?
The student who visited in 2006 had 4400 Mexican pesos remaining.

Currently (2006), the marine biologist can receive over 6,500 USD is she converts her currency. In the future, however; she will receive less USD. It may even reach the point that she actually loses
