[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. The answer is 2.

[Question]Janessa has a plan to give her brother Dexter his first collection of baseball cards. She currently has 4 cards in addition to the 13 that her father gave her. She ordered a collection of 36 cards from eBay. After inspecting the cards she found 4 cards are in bad shape and decides to throw them away. Janessa ended up giving Dexter 29 cards. How many cards did Janessa keep for herself?
[Answer]Janessa starts with 4 cards + 13 cards = 17 cards. She adds 17 cards + 36 cards = 53 cards from the eBay purchase. Janessa decides to throw away 53 cards - 4 cards = 49 cards due to damage. After giving Dexter the present we know that Janessa kept 49 cards - 29 cards = 20 cards for herself. The answer is 20.
Q: Building one birdhouse requires 7 planks and 20 nails. If 1 nail costs $0.05, and one plank costs $3, what is the cost, in dollars, to build 4 birdhouses?
A: The cost of the planks for one birdhouse is 7 * 3 = $21. And the nails are a cost of 20 * 0.05 = $1 for each birdhouse. So to build one birdhouse one will need 21 + 1 = $22. So the cost of building 4 birdhouses is at 4 * 22 = $88. The answer is 88.
Question: Oliver has 4 friends that he is inviting to a party at the arcade. Game tokens cost 30 for $1. Each game costs 2 tokens. If he wants all his friends to get to play 60 games each, how much will it cost?
Answer:
He needs to buy enough tokens for 240 games because 4 x 60 = 240. He needs to buy 480 tokens because 2 x 240 = 480. He needs to spend 160 because 480 / 30 = 16. The answer is 16.
