Question

How much money will it cost you to drive 100 miles if your car gets 25.70 miles per gallon and gas costs $3.309/gallon?

Answer 1

If the car gets 25.70 miles per gallon, it will use 100 miles / 25.70 miles/gallon = 3.89 gallons of gas to drive 100 miles.

If one gallon costs $3.309, it will cost $3.309 × 3.89 gallons = $12.87 to drive 100 miles.

Answer: $12.87
