Q: Stan can type 50 words per minute. He needs to write a 5-page paper. Each page will contain 400 words. Each hour that he types he needs to drink 15 ounces of water. How much water does he need to drink while writing his paper?
A: Stan needs to write 2,000 words because 5 x 400 = 2,000. This will take him 40 minutes because 2,000 / 50 = 40. He drinks 1 / 4 an ounce per minute because 15 / 60 = 1 / 4. He will drink 10 ounces of water while writing the paper because 40 x (1 / 4) = 10. The answer is 10.
Question: Charlotte is a dog walker and is creating a schedule for all of her clients this week. Each dog is walked separately. On Monday, she needs to walk 4 poodles and 2 Chihuahuas. On Tuesday, she walks the same amount of Chihuahuas but isn't sure how many poodles she should walk. On Wednesday, she walks 4 Labradors. It takes 2 hours to walk a poodle, 1 hour to walk a Chihuahua, and 3 hours to walk a Labrador. If she has time for a total of 32 hours spent in dog-walking this week, how many poodles can Charlotte walk on Tuesday?
Answer: On Monday, she spends 4 poodles * 2 hours = 8 hours walking poodles. On Monday, she spends 2 Chihuahuas * 1 hour = 2 hours walking Chihuahuas. On Tuesday, she spends 2 Chihuahuas * 1 hour = 2 hours walking Chihuahuas. On Wednesday, she spends 4 Labradors * 3 hours = 12 hours walking Labradors. Over the week, this is a total of 8 + 2 + 2 + 12 = 24 hours spent dog - walking. This means she still has 32 maximum hours – 24 used hours = 8 hours available for dog - walking. Therefore, she can walk 8 hours / 2 hours per poodle = 4 poodles on Tuesday. The answer is 4.
[Question]Josh built his little brother a rectangular sandbox. The perimeter of the sandbox is 30 feet and the length is twice the width. What is the width of the sandbox?
[Answer]There are four sides to a rectangle, the width is W and so the length is 2W, and we can put that in this equation: W + W + 2W + 2W = 30 feet. If we add the sides together, we get 6W = 30 feet. To find W, we divide both sides by 6, like this: 6W / 6 = 30 feet / 6, so W = 5 feet. The answer is 5.

Question: Every morning, Carla puts 79 apples in her backpack to eat for lunch. Unfortunately, Buffy stole some of Carla's apples on the school bus, and 26 apples fell out of a hole on the bottom. So at lunchtime, Carla only had 8 apples remaining. How many apples did Buffy steal from Carla?
Answer: Let B be the number of apples that Buffy stole. Then 79 - B - 26 = 8. Combining constants produces 53 - B = 8. Adding B to both sides produces 52 = B + 8. Thus the number of apples stolen by Buffy is B = 53 - 8 = 45. The answer is 45.
