Question 1038115: Anna is a student who frequently uses her American debit card to make purchases when traveling abroad. When she makes a purchase, the bank converts the purchase price at a daily foreign exchange rate and than charges a 3% fee on the converted price.
Anna also converts cash from one currency to another at her bank. To convert cash into a different currency, her bank uses the daily foreign exchange rates and charges a 2.5% fee on the converted cost.
In Mexico, Anna used her debit card for a purchase that cost 235 pesos. The bank than charged her card 18.62 U.S dollars, including the 3% conversion fee. What foreign exchange rate, in Mexican pesos per U.S dollar, did the bank use for Anna's purchase?

You can put this solution on YOUR website! The conversion fee is 3%, so 1.03 times her money is 18.62. Therefore, the amount of her purchase was:
18.62/1.03=$18.08
235/18.08=13 pesos to the dollar exchange rate!!!!!!!!!!!!!
