Question: Aubree saw 20 beavers and 40 chipmunks by a tree when going to school and scared them away when they saw her. While coming back from school, she realized the number of beavers had doubled and the number of chipmunks had decreased by 10. What's the total number of animals she saw that day?
Answer: When going to school, she saw 40 + 20 = 60 animals. The number of beavers doubled to 20 * 2 = 40 beavers. The number of chipmunks decreased to 40 - 10 = 30 chipmunks. The total number of animals she saw on that day is 30 + 40 + 60 = 130 animals. The answer is 130.

Question: Sweet Hope hosts a casino with 3 roulette tables labeled A, B, and C. At 6:00 pm, Table B had twice as much money on it as table C, which had $20 more than table A. If there was $40 on table A, how much money was there on all the tables?
Answer: If table C had $20 more than table A, then table C had $20 + $40 = $60. Roulette tables A and C had $60 + $40 = $100. Table B had twice as much money on it as table C, meaning table B had $60 * 2 = $120. Together, the three roulette tables had $120 + $100 = $220. The answer is 220.

Question: Mark got a 5% raise at his job. Before the raise, he earned 40 dollars per hour. He works 8 hours per day for 5 days per week. His old bills used to be 600 dollars a week but he decided to add a hundred dollar a week personal trainer. How much does he have leftover a week?
Answer:
After the raise he earns 40 * 1.05 = 42 dollars an hour. He works 8 hours per day so earns 42 * 8 = 336 per day. He works 5 days per week so he earns 336 * 5 = 1680 a week. His expenses after adding the personal trainer are 600 + 100 = 700 a week. So he has 1680 - 700 = 980 left over. The answer is 980.
