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?
