Q: Miggy's mom brought home 3 bags of birthday hats. Each bag has 15 hats. Miggy accidentally tore off 5 hats. During the party, only 25 hats were used. How many hats were unused?
A: There are a total of 15 x 3 = 45 hats in 3 bags. Since 5 tore off, only 45 - 5 = 40 hats were left. Thus, 40 - 25 = 15 hats were unused. The answer is 15.
Question: Tommy's mother lets him ride his bike 2 blocks north of his block, 3 blocks east, 2 blocks west, and 2 blocks south. His friend's father lets his friend ride his bike 80 square blocks. How many times greater is the area his friend can ride in compared to Tommy?
Answer: Tommy's area is 5 blocks wide because 3 + 2 = 5. His area is 4 blocks tall because 2 + 2 = 4. The total area is 20 square blocks because 5 x 4 = 20. His friend's area is 4 times bigger because 80 / 20 = 4. The answer is 4.
[Question]Bonnie and Samuel went to the market together. Bonnie bought 8 apples. Samuel bought 20 more apples than Bonnie. Samuel then ate half of them and used 1/7 of them to make apple pie. How many apples does Samuel have left?
[Answer]Samuel bought 20 + 8 = 28 apples. Samuel ate 28 / 2 = 14 apples. Samuel used 28 / 7 = 4 to make apple pie. Samuel has 28 - 14 - 4 = 10 apples left. The answer is 10.
Q: Elsie has a specific amount of wet wipes in a container in the morning. Throughout the day, she refills the container with 10 more wipes after using up 20. By nighttime, she only has 60 wipes left. How many wipes were in the container in the morning?
A: Let w be the number of wet wipes Elsie had in the morning. Throughout the day, she used w - 20 wet wipes. Once that happened, she had to refill the container resulting in w - 20 + 10 = w - 10 wet wipes. By nighttime, she had w - 10 = 60 wipes. So then, w = 60 + 10 = 70. She started with w = 70 wipes. The answer is 70.

Using buy - 1 - get - 1 - free pricing, it costs 1 * $5 = $5 to buy 2 triple cheese pizzas. At $5 per 2 pizzas, it costs $5 / 2 = $2.5 per triple cheese pizza. Using buy - 2 - get - 1 - free pricing, it costs 2 * $5 = $10 to buy 3 meat lovers pizzas. At $10 per three pizzas, it cost $10 / 3 = $3 and $1 / 3 per meat lovers pizza. With the buy - 1 - get - 1 - free pricing, 10 triple cheese pizzas are 10 * $2.5 = $25. With the buy - 2 - get - 1 - free pricing, 9 meat lovers pizzas are 9 * ($3 + $1 / 3) = $30. In total, for 10 triple cheese and 9 meat lovers pizzas, it will cost $25 + $30 = $55. The answer is 55.
