My question is: Winston had 10 gallons of gas in his car's gas tank. He drives to the store and uses 6 gallons of gas. Then he drives to the doctor's office and uses 2 gallons of gas. If the tank can hold up to 12 gallons of gas, how many gallons of gas will Winston need to refill the entire tank? Your thoughts:
After driving to the store and doctor's office, Winston has 10 - 6 - 2 = 2 gallons of gas left in the tank. To refill the entire tank, Winston needs 12 - 2 = 10 gallons of gas. The final answer: 10.
