[Question]Elyse had 100 pieces of gum. She gave half to her brother Rick. He gave half of his to his friend Shane. Shane chewed 11 pieces of gum. How many pieces does Shane have left?
[Answer]Elyse gave half of her 100 pieces of gum, or 100 / 2 = 50 pieces of gum, to Rick. Rick gave half of his 50 pieces of gum, or 50 / 2 = 25 pieces of gum, to Shane. Shane had 25 pieces of gum and chewed 11, so he had 25 – 11 = 14 pieces of gum left. The answer is 14.
Q: Toby, the Alaskan Malamute, can pull a sled at a speed of 20 miles per hour if the sled is unloaded, but he pulls the same sled at a speed of 10 miles per hour if the sled is fully loaded. If Toby takes a continuous 4-part journey, first pulling the loaded sled for 180 miles, then pulling the unloaded sled for 120 miles, then pulling the loaded sled 80 miles, and finally, pulling the unloaded sled another 140 miles, how many hours in total will Toby spend pulling the sled?
A: Pulling a loaded sled at 10 mph for 180 miles takes 180 / 10 = 18 hours. Pulling an unloaded sled at 20 mph for 120 miles takes 120 / 20 = 6 hours. Pulling a loaded sled at 10 mph for 80 miles takes 80 / 10 = 8 hours. Pulling an unloaded sled at 20 mph for 140 miles takes 140 / 20 = 7 hours. In total, Toby will have pulled the sled for 18 + 6 + 8 + 7 = 39 hours. The answer is 39.
Question: Aubrey has a deck of cards with 52 cards in it. She then adds two additional cards to the deck. If she splits the deck evenly among herself and two other players, how many cards does each player have?
Answer: The deck has 54 cards because 52 + 2 = 54. There are three players because 1 + 2 = 3. Each player gets 18 cards because 54 / 3 = 18. The answer is 18.

On Wednesday, he reads the third book. If he has read a total of 51 pages from Monday to Wednesday, how many pages did he read on Wednesday?

Question: Jill and Bob want to finally buy a house for themselves, so they went with a real estate agent to see some houses before making a decision. The first house was not too far from their work and the price was accessible. The second house was really big and Jill loved it but was twice as expensive as the first one and was way over their budget. They ended up buying the first one, knowing that the price of both houses altogether is $600,000. How much did Jill and Bob end up paying for their new house?
Answer:
Let C be the cost of the first house. The cost of the second house is 2C. The cost of the two houses together is C + 2C = $600,000. 3C = $600,000. C = $600,000 / 3 = $200,000. The answer is 200000.
