Which Gas Is Cheapest?
Here's three photographs of gas station signs. The one on the left was taken in Mississauga, Ontario, Canada and the two on the right were taken in Bethesda, Maryland, USA. The Bethesda gas stations are one block apart.
Assuming that the photos were taken on the same day (Wednesday, April 8, 2009), which station has the cheapest gas if you pay by credit card?
