L'oreal car travels 420 miles on a full tank of gas her tank can hold 14 gallons. laila car can travel 435 miles on 15 gallons. which car gets better mileage? pls help

L’oreal’s car can gets better mileage because you have to divide both the miles and the amount of gallons they carried. L’oreal: 420 divided by 14 is 30 = 30 miles per gallon. Laila: 435 divided by 15 = 29 miles per gallon. But since we have to even out the amount of gallons they both carry, we can either take away 29 to the 435 (Laila), or add 30 to the 420(L’oreal). 420 + 30 = 450. 435 - 29 = 406. 420 > 406 = 450 > 435. L’oreal has the better mileage
