the answer is 48 but I don't know how to solve it Please Help!

You can put this solution on YOUR website! After the first third of the car's gas has been used, we see that there are 10+9+13 = 32 gallons left.
Therefore, 32 = (2/3)x where x is the number of gallons in a full tank. Multiplying by 3/2, we get x = 48 gallons.
