You just came back from Canada, where the Canadian dollar was worth $.80. You still have 500 Canadian dollars from your trip and could exchange them for dollars at the airport, but the airport foreign exchange desk will only buy them for $.75. Next week, you will be going to Mexico and will need pesos. The airport foreign exchange desk will sell you pesos for $.15 per peso. How many pesos will you receive if you exchange Canadian dollars at the airport?
