Ethan's car can drive 30 miles per gallon of gasoline. Gasoline costs $4 per gallon, including tax. Ethan drove 180 miles on a trip. What was the total cost, in dollars, of gasoline that the car used for Ethan's trip?
24$ I believe is the answer You divide the total number of miles driven, to the number of miles per gallon . 180 divided by 30 = 6. Then multiply the answer 6 times dollars per gallon 4$ • 6 = 24 Your answer is 24 :)
