Lizzy: Mr. Finnegan has 3 tanks with a capacity of 7000 gallons, 5000 gallons, and 3000 gallons, respectively. If he fills the first tank up to 3/4 full, the second tank with water up to 4/5 of its capacity, and the third tank up to half of its capacity, how many gallons in total are in the tanks?.
Me: Hmmm, let me think. I think this is the detailed solution:

The capacity of the first tank is 7000 gallons, and if it is filled up to 3 / 4 full, it carries 3 / 4 * 7000 = 5250 gallons. When the second tank is filled up to 4 / 5 of its capacity, it carries 4 / 5 * 5000 = 4000 gallons. The total amount of water in the first two tanks is 5250 + 4000 = 9250 gallons. If Mr. Finnegan fills the third tank with water up to half its capacity, the tank fills up with 1 / 2 * 3000 = 1500 gallons. In total, the three tanks have 9350 + 1500 = 10850 gallons of water. Final answer: 10850.
