[Question]: A library cabinet houses five ancient scrolls. The first scroll is 4080 years old. If each scroll is older than the last by half as many years as the last scroll's age, how old is the fifth scroll?
[Answer]: The second scroll is 4080 + 4080 / 2 = 4000 + 2040 = 6120 years old. The third scroll is 6120 + 6120 / 2 = 6120 + 3060 = 9180 years old. The fourth scroll is 9180 + 9180 / 2 = 9180 + 4590 = 13770 years old. The fifth scroll is 13770 + 13770 / 2 = 13770 + 6885 = 20655 years old.
So the answer is 20655.

[Question]: Josh had 100 gummy bear candies. He decided to give his 3 siblings 10 candies each. Then he gave half of the remaining candies to his best friend. If he only wants to eat 16 gummy bear candies, how many candies are left to be shared with others?
[Answer]: Josh gave a total of 3 x 10 = 30 candies to his siblings. He was then left with 100 - 30 = 70 candies. He gave 70 / 2 = 35 candies to his best friend. So he had 70 - 35 = 35 candies left. Since he only wants to eat 16 candies, there are still 35 - 16 = 19 candies left to be shared with others.
So the answer is 19.

[Question]: John injures his shoulder while lifting weights. After the injury, his bench press goes down 80%. After a bit of training, he manages to triple the weight he can bench. If he started with a 500-pound bench press, what is it now?
[Answer]:
He lost 500 * .8 = 400 pounds from his bench. So his bench went to 500 - 400 = 100 pounds. After training it increased to 100 * 3 = 300 pounds.
So the answer is 300.
