Question
I've been working on this problem for "hours" and I can't quite figure out how to solve it; can anyone help plzzz? I would appreciate it. :)
Two college students went on spring break to Guadalajara, Mexico. 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 spent five nights in a hotel, which student had more pesos left over? Exactly how many did that student have?

2002:
9 * 500 = 4,500 pesos
5 * 200 = 1,000
4,500 - 1,000 = 3,500 pesos left
2006:
11 * 500 = 5,500 pesos
5 * 220 = 1,100
5,500 - 1,100 = 4,400 pesos left
9 * 500 = 4,500 pesos
5 * 200 = 1,000
4,500 - 1,000 = 3,500 pesos left
2006:
11 * 500 = 5,500 pesos
5 * 220 = 1,100
5,500 - 1,100 = 4,400 pesos left
