My question is: James has barrels that he uses to store water. They store 3 gallons more than twice as much as a large cask. If he has 4 barrels and a cask stores 20 gallons, how much water can he store? Your thoughts:
A barrel stores 20 * 2 + 3 = 43 gallons. So he can store 4 * 43 = 172 gallons. The final answer: 172.
