My price of gas was from an American site which quoted the average price of each state for the day, the price quoted by that site was $1.90. Prices down there are likely the same as up here, some places higher some lower, thought using average price would be fair. As for exchange rates, I am able to buy things on my credit card with no exchange fees, so I used the price of .71 as the exchange price, which converts into $1.4084, didn't check my math so there could be a mistake.

Just thought I would explain how and why I used the numbers I did.
