Question

Darnell's car used 8 gallons of gasoline to travel 340 miles. After a mechanic worked on the car, it used 7 gallons of gasoline to travel 350 miles. If the price of gasoline was approximately $4.00 per gallon, how much less, to the nearest cent per mile, did it cost to run the car after the mechanic worked on it?

Answer 1

7 gallons = 350
1 gallon of gas = 50 miles
0.02 gallon = 1 mile
4.00*0.02= 0.08
0.08 to run the car
