Q: Sarah is in charge of making 2 copies of a contract for 9 people that will be in a meeting. The contract is 20 pages long. How many pages will Sarah copy?
A: Every person needs 2 copies and there are 9 people in the meeting so she needs 2 * 9 = 18 copies. The contract is 20 pages long and she has to make 18 copies so she will end up copying 20 * 18 = 360 pages. The answer is 360.
Question: Rachel makes $12.00 as a waitress in a coffee shop. In one hour, she serves 20 different people and they all leave her a $1.25 tip. How much money did she make in that hour?
Answer: She served 20 people and they all tipped her $1.25 so she made 20 * 1.25 = $25.00 in tips. She makes $12.00 an hour and she made $25.00 in tips so she made 12 + 25 = $37.00 in one hour. The answer is 37.
[Question]Brian goes fishing twice as often as Chris, but catches 2/5 times fewer fish than Chris per trip. If Brian caught 400 fish every time he went fishing, how many fish did they catch altogether if Chris went fishing 10 times?
[Answer]If Brian caught 400 fish in one trip, he caught 2 * 400 = 800 fish in two trips. Since Brian catches 2 / 5 times less fish than Chris per trip, Chris catches 2 / 5 * 400 = 160 more fish in one fishing trip. Chris's total number of fish in one trip is 400 + 160 = 560 fish. In 10 trips, Chris catches 560 * 10 = 5600 fish. If in his two trips Brian catches 800 fish, and he goes fishing twice as often as Chris, if Chris goes fishing 10 times, Brian will catch 800 * 10 = 8000 fish. The total number of fish they'll catch if Chris goes fishing ten times is 8000 + 5600 = 13600. The answer is 13600.
Q: A pad of paper comes with 60 sheets. Evelyn uses a pad of paper writing notes at work every week. She takes Monday and Friday off from work. How many sheets of paper does she use per day at work?
A: Evelyn takes two days a week off from work, so she is at work 7 - 2 = 5 days a week. Thus, she uses 60 / 5 = 12 sheets of paper per day at work. The answer is 12.
Question: Carla is dividing up chores for her two kids, Anna and Billy. She wants each of them to spend the same number of minutes working. Sweeping takes 3 minutes per room, washing the dishes takes 2 minutes per dish, and doing laundry takes 9 minutes per load. If Anna does the sweeping for 10 rooms and Billy does two loads of laundry, how many dishes should Billy wash so they spend the same amount of time doing chores?
Answer: First find the total time Billy spends on laundry: 2 loads * 9 minutes / load = 18 minutes. Then find the total time Anna spends sweeping: 3 minutes / room * 10 rooms = 30 minutes. Then find how much longer Anna has already worked than Billy: 30 minutes - 18 minutes = 12 minutes. Then divide the difference in work time by the time to wash one dish to find the number of dishes Billy has to wash to work the same amount of time as Anna: 12 minutes / 2 minutes / dish = 6 dishes. The answer is 6.
Q: Nancy can hula hoop for 10 minutes. Casey can hula hoop 3 minutes less than Nancy. Morgan can hula hoop three times as long as Casey. How long can Morgan hula hoop?
A:
Casey can hula hoop 3 minutes less than Nancy so she can hula hoop for 10 - 3 = 7 minutes. Morgan can hula hoop three times as long as Casey, who can hula hoop for 7 minutes, so she can hula hoop for 3 * 7 = 21 minutes. The answer is 21.
