Question: Gentry assembled a new 24 foot round pool in her backyard. To fill the pool with water, she used four hoses. Two of the hoses each deliver water at a rate of 2 gallons per minute. The other two hoses each deliver water at a rate of 3 gallons per minute. With a volume of 15,000 gallons, how many hours will it take to fill the pool?
Answer: Each of the two hoses delivers water at a rate of 2 gallons per minute, for a combined total of 2 * 2 = 4 gallons of water per minute. The other two hoses each deliver water at a rate of 3 gallons per minute, for a combined total of 2 * 3 = 6 gallons of water per minute. Thus, all four hoses deliver a combined total of 4 + 6 = 10 gallons of water per minute. With a volume of 15,000 gallons, it would take 15,000 / 10 = 1500 minutes to fill the pool. Converting to hours, it will take 1500 / 60 = 25 hours to fill the pool. The answer is 25.

Question: There were 133 people at a camp. There were 33 more boys than girls. How many girls were at the camp?
Answer: If there were 33 fewer boys at camp, there would be the same number of both boys and girls or 133 - 33 = 100 people. That means that there were 100 / 2 = 50 girls at the camp. The answer is 50.

Question: Vanessa wants to buy a dress she saw at the mall, which costs $80, and she already has $20 in savings. Her parents give her $30 every week, but she also spends $10 each weekend at the arcades. How many weeks will she have to wait until she can gather enough money to buy the dress?
Answer: Vanessa needs $80 – $20 = $60 to buy the dress. She manages to gather $30 - $10 = $20 each week. The number of weeks she has to wait is 60 ÷ 20 = 3 weeks. The answer is 3.

Question: 8 jumbo scallops weigh one pound and cost $24.00 a pound. Nate is pairing 2 scallops with a corn bisque as a light summer dinner. He’s cooking for 8 people. How much will the scallops cost?
Answer:
He’s cooking for 8 people and wants to serve 2 scallops per person so he needs 8 * 2 = 16 scallops. 8 jumbo scallops come in 1 pound and he needs 16 scallops so he will need 16 / 8 = 2 pounds of scallops. A pound of scallops weigh $24.00 and he needs 2 pounds so it will cost him 24 * 2 = $48.00 for scallops. The answer is 48.
