Q: Billy and Tiffany are having a contest to see how can run the most miles in a week. On Sunday, Monday, and Tuesday, Billy runs 1 mile each day and Tiffany runs 2 miles each day. On Wednesday, Thursday, and Friday, Billy runs 1 mile each day and Tiffany runs a 1/3 of a mile each day. On Saturday Tiffany assumes she's going to win and takes the day off. How many miles does Billy have to run on Saturday to tie Tiffany?
A: Billy has already run 6 miles because 1 plus 1 plus 1 plus 1 plus 1 plus plus 1 equals 6. Tiffany has already run 7 miles because 2 plus 2 plus 2 plus 1 / 3 plus 1 / 3 plus 1 / 3 equals 7. Billy has to run 1 mile to tie Tiffany because 7 minus 6 equals 1. The answer is 1.
Question: Bert's golden retriever has grown tremendously since it was a puppy. At 7 weeks old, the puppy weighed 6 pounds, but doubled in weight by week 9. It doubled in weight again at 3 months old, and doubled again at 5 months old. Finally, the dog reached its final adult weight by adding another 30 pounds by the time it was one year old. What is the dog's full adult weight, in pounds?
Answer: At 7 weeks old, the puppy weighed 6 pounds, but doubled in weight by week 9 to reach a weight of 6 * 2 = 12 pounds. It doubled in weight again at 3 months old to reach a weight of 12 * 2 = 24 pounds. It doubled in weight again at 5 months old to reach a weight of 24 * 2 = 48 pounds. And it reached its full adult weight by adding another 30 lbs to reach a final weight of 48 + 30 = 78 pounds. The answer is 78.
[Question]Tara is saving up to buy a new clarinet. She already has $10 saved. The clarinet costs $90. She plans to sell her old books to make the money. She sells each book of hers for $5. However, when she is halfway towards her goal, she loses all her savings and has to start over. How many books does she sell in total by the time she reaches her goal?
[Answer]Halfway towards her goal is $45 because 90 / 2 = 45. She sells $35 worth of books before she loses the money because 45 - 10 = 35. She sells 7 books before losing her money because 35 / 7 = 5. She then sells 18 books because 90 / 5 = 18. She sells 25 books in total because 18 + 7 = 25. The answer is 25.
