[Question]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?
[Answer]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.
Q: Claire won a $100 gift card to her favorite coffee shop. She wants to treat herself to a latte that cost $3.75 and a croissant for $3.50 every morning for a week. She also plans to buy 5 cookies that cost $1.25 each. How much money will be left on her card after a week of coffee and pastry?
A: Every day she buys $3.75 latte and $3.50 croissant for a total of 3.75 + 3.50 = $7.25 per day. If she spends $7.25 a day for 7 days she will spend 7.25 * 7 = $50.75 in one week. If she buys 5 cookies at $1.25 each she will spend 5 * 1.25 = $6.25. Her gift card is for $100 and she spends $50.75 and an additional $6.25 that will leave her with 100 - 50.75 - 6.25 = $43.00 on her gift card. The answer is 43.
Question: James does chores around the class. There are 3 bedrooms, 1 living room, and 2 bathrooms to clean. The bedrooms each take 20 minutes to clean. The living room takes as long as the 3 bedrooms combined. The bathroom takes twice as long as the living room. He also cleans the outside which takes twice as long as cleaning the house. He splits the chores with his 2 siblings who are just as fast as him. How long, in hours, does he work?
Answer: It takes 3 * 20 = 60 minutes to clean the living room. So it is 60 / 60 = 1 hour. The bathroom takes 1 * 2 = 2 hours. So all together the inside takes 1 + 1 + 2 = 4 hours. The outside takes 4 * 2 = 8 hours. So the chores take 4 + 8 = 12 hours. He splits it 1 + 2 = 3 ways. So he works 12 / 3 = 4 hours. The answer is 4.
[Question]The pizza delivery person has 12 pizzas to deliver. If two of the stops are for orders of two pizzas and the rest are for single pizzas, how many minutes per stop does the delivery person need to average to deliver all of the pizzas in 40 minutes?
[Answer]If two pizzas will be delivered at two of the stops, the total number of stops will be 12 - 2 = 10 stops. If there are 10 stops in 40 minutes, then the delivery person needs to average 40 / 10 = 4 minutes per stop. The answer is 4.
Q: Ms. Hatcher teaches 20 third-graders and a number of fourth-graders that is twice the number of third-graders. Her co-teacher asked her to substitute for her fifth-grade class that has half as many students as the number of third-graders. How many students did Ms. Hatcher teach for the day?
A: Ms. Hatcher taught 20 x 2 = 40 fourth graders for the day. She taught 20 / 2 = 10 fifth - graders as a substitute teacher for the day. Therefore, she taught 20 + 40 + 10 = 70 students for the day. The answer is 70.
