Answer 1

Answer:

1. 2006 Student

2. 4400 pesos left

Explanation:

If each student had $500 to spend and In 2002, the exchange rate of MXN/USD (Mexican pesos to U.S. dollars) was 9 and In 2006, the exchange rate was 11.

If the hotel room in Guadalajara cost 200 pesos per night in 2002 and 220 pesos in 2006 and each student spent five nights in a hotel, which student had more pesos left over:

Student A - 2002

Spent 5 nights x 200 pesos = 1000 pesos

Total pesos  = $500 x 9 = 4500 pesos

Pesos left = 4500 - 1000 = 3500 pesos

Student B - 2006

Spent 5 nights x 220 pesos = 1100 pesos

Total pesos  = $500 x 11 = 5500 pesos

Pesos left = 5500 - 1100 = 4400 pesos
