Q: John has a large water collection tank. The tank can hold 200 gallons. It weighs 80 pounds empty. A rainstorm fills it to 80% of capacity. If a gallon of water weighs 8 pounds, how much does it weigh now?
A: The tank has 200 * .8 = 160 gallons of water in it. That water weighs 160 * 8 = 1280 pounds. So in total it weighs 1280 + 80 = 1360 pounds. The answer is 1360.

Q: If a bunny comes out of its burrow 3 times per minute, calculate the combined number of times 20 bunnies at the same pace will have come out of their burrows in 10 hours.
A: If a bunny comes out of its hole three times in a minute, in an hour, with 60 minutes, the bunny will come out of the hole 60 * 3 = 180 times. In 10 hours, a bunny will come out of their hole 180 * 10 = 1800 times. The combined time that 20 bunnies coming out of their holes will have taken in 10 hours is 1800 * 20 = 36000 times. The answer is 36000.

Q: Joanna and Jacques had 40 and 60 gumballs, respectively, in their dishes. They then purchased 4 times the number of gumballs they had initially and added these to their dishes. If they decided to put together their gumballs and shared them equally, how many gumballs did each get?
A:
When Joanna purchased 4 times the number of gumballs she initially had, she added 40 * 4 = 160 gumballs to her dish. The total number of gumballs Joanna had in her dish after buying 160 more is 160 + 40 = 200. At the same time, Jacques bought 60 * 4 = 240 new gumballs. When Jacques added his new 240 gumballs to his dish, the total number of gumballs increased to 240 + 60 = 300 gumballs. When they decided to put together their gumballs, they had 300 + 200 = 500 gumballs altogether. After sharing equally, each person got 500 / 2 = 250 gumballs. The answer is 250.
