Question

You're driving into Canada and trying to decide whether to fill your gas tank before or after crossing the border. Gas in the United States costs $2.58/gallon, in Canada it's $1.29/L, and the Canadian dollar is worth 79¢ in U.S. currency. Where you should fill up?

Answer 1

Answer:

It is more convenient to fill up in the United States.

Step-by-step explanation:

We convert a US gallon to liters:

1 Gallon equals 3.78541 liters.

Therefore, 1 US Gallon costs (3.78541) x (1.29) = 4.8831789 Canadian dollars.

Now we convert the price of a US gallon in Canadian territory to US dollars:

4.8831789 * 0.79 = 3.85771133 US dollars.

Conclusion: A gallon purchased in the United States costs 2.58 US dollars, while a gallon in Canada is equivalent to 3.85771133 US dollars. This way it is more convenient to fill up in the United States.
