conversations.value: Carol fills up her gas tank as she is driving home for college, which is 220 miles away. She can get 20 miles to the gallon in her car, which has a 16-gallon gas tank. How many more miles will she be able to drive after she gets home and without filling her tank again?

conversations.value: Divide the remaining miles of the trip by the miles per gallon her car gets. 220 miles / 20 miles/gallon = 11 gallons
  Subtract the gallons used for the trip from the size of her gas tank. 16 gallons - 11 gallons = 5 gallons
  Multiply the remaining number of gallons by the car's gas mileage. 5 gallons x 20 miles/gallon = 100 miles
