Lizzy: Timmy, Tommy and Tina are filling up a kiddie pool in their backyard. Each has a pail they fill with water from a house before dumping it into the pool. If Timmy's pail holds twice as much water as Tommy's, and Tommy's holds 2 gallons more than Tina's, and Tina's is 4 gallons, how much water do the three of them fill the pool with after 3 trips each?.
Me: Hmmm, let me think. I think this is the detailed solution:
If Tina's pail holds 4 gallons and Tommy's holds 2 more gallons than hers, that means Tommy's holds 4 + 2 = 6 gallons. If Timmy's pail holds twice as much as Tommy's 6 - gallon pail, that means it holds 6 * 2 = 12 gallons. Therefore, in 1 trip that means all three move a total of 4 + 6 + 12 = 22 gallons. In three trips, that means they would move a total of 22 * 3 = 66 gallons. Final answer: 66.
