Question

You drive up to Canada and notice that gas costs $1.31 per liter. The Canadian dollar is worth U.S. $1.02. How much will it cost you in american dollars to fill up your 12 gallon tank? What id the price per gallon up in Canada in American dollars?

Answer 1

1 litre costs 1.31
1 gallon = 3.7854 L
12 gallons = 12(3.7854) L
12 gallons cost CND $1.31(12)(3.7854) = CN $59.51

1 CND = US 1.02
C 59.51= US (1.02)(59.51) = $60.70

cost per gallon in US$ = 60.70/12 = $5.06



actual cost TODAY:
12 gallons cost 12(3.7854)(1.06) = $48.15
CND $1 = US$ .80
so C$ 48.15 = US $38.52

cost per gallon = US $ 3.21
