[Question]: There are 35 books on the cart. There are five fiction books, 4 more non-fiction books than fiction books, 2 times as many autobiographies as fiction books, and the rest picture books. How many books were picture books?
[Answer]: There are 5 + 4 = 9 non - fiction books on the cart. There are 2 * 5 = 10 autobiographies on the cart. There are 5 + 9 + 10 = 24 fiction, non - fiction, and autobiography books on the cart. There are 35 - 24 = 11 picture books on the cart.
So the answer is 11.

[Question]: Shelby was having a movie party for her birthday. She and her mom made a dozen bags of buttered popcorn and 10 bags of caramel popcorn. Her brother Alan took 3 bags of buttered popcorn and 1 bag of caramel popcorn for his friends. How many bags of popcorn does Shelby have left for the party?
[Answer]: Shelby and her mom made 12 bags of buttered popcorn + 10 bags of caramel popcorn = 22 bags. Of those 22 bags, her brother took 3 bags of buttered popcorn + 1 bag of caramel popcorn = 4 bags. So now Shelby has 22 bags – 4 bags = 18 bags of popcorn left.
So the answer is 18.

[Question]: Michael is stuck in an elevator that is slowly moving to the bottom floor. The elevator needs to move down 20 floors to reach the bottom. It takes 15 minutes for the elevator to travel down the first half of the floors. The elevator then takes 5 minutes per floor to travel down the next 5 floors. It then takes 16 minutes per floor for the elevator to finish traveling down the final 5 floors. In hours, how long did it take for the elevator to reach the bottom?
[Answer]:
Over 5 of the floors, it takes the elevator 5 floors * 5 minutes per floor = 25 minutes to lower. Over the final 5 floors, it takes the elevator 5 floors * 16 minutes per floor = 80 minutes to lower. So in total, the elevator takes 15 minutes in the first half + 25 minutes in the next five floors + 80 minutes in the final five floors = 120 minutes to lower to the bottom. This is the same as 120 minutes / 60 minutes per hour = 2 hours.
So the answer is 2.
