You just came back from Canada, where the Canadian dollar was worth 0.43. You still have C$200 from your trip and could exchange them for pounds at the airport, but the airport foreign exchange desk will only buy them for 0.40. Next week, you will be going to Mexico and will need pesos. The airport foreign exchange desk will sell you pesos for 0.055 per peso. You met a tourist at the airport who is from Mexico and is on his way to Canada. He is willing to buy your C$200 for 1500 New Pesos. Should you accept the offer or cash the Canadian dollars in at the airport? Explain.
