Question: Alison bought some storage tubs for her garage. She bought 3 large ones and 6 small ones, for $48 total. If the large tubs cost $6, how much do the small ones cost?
Answer: Let t be the price of the small tubs. 3 * 6 + 6 * t = 48. 18 + 6 * t = 48. 6 * t = 48 - 18 = 30. 6t = 30. t = 5 dollars for each small tub. The answer is 5.
[Question]Brian loves watching animal videos online. He watches a 4-minute video of cats. He then watches a video twice as long as the cat video involving dogs. He finishes up his video watching for the day by watching a video on gorillas that's twice as long as the previous two videos combined. How many minutes does Brian spend watching animal videos?
[Answer]Brian begins by watching a 4 - minute video, and since the second video is twice as long that means the second video is 4 * 2 = 8 minutes. The first two videos combined therefore for a 4 + 8 = 12 minute run time. Since the third video is twice as long as the first two videos put together, that means it is 12 * 2 = 24 minutes in length. The total length of time spent is therefore 24 + 12 = 36 minutes. The answer is 36.
Q: John uses a 75-watt electric fan for 8 hours a day. How much kWh of electric energy does he consume per month (30 days) for using the electric fan?
A: In a day, John uses 75x 8 = 600 watts. So in a month, he uses 600 x 30 = 18 000 watts. Since there are 1000 watts in 1 kilowatt, then John uses 18000 / 1000 = 18. The answer is 18.
Question: Twice Betty's age is the cost of a pack of nuts. Doug, Betty's friend, is 40 years old. If the sum of their ages is 90, and Betty wants to buy 20 packs of the nuts, calculate the amount of money she'll pay for the packs of nuts.
Answer: If Doug, Betty's friend, is 40 years old, and the sum of their ages is 90, Betty is 90 - 40 = 50 years old. Since twice Betty's age is the cost of a pack of nuts, a pack of nuts is sold at 2 * $50 = $100. If Betty wants to buy 20 packs of the nuts, she'll have to pay 20 * $100 = $2000. The answer is 2000.
Q: Jane, Kyla, and Anthony have summer jobs in a resort. Their task is to fold guests' towels. Jane can fold 3 towels in 5 minutes. Kyla can fold 5 towels in 10 minutes, and Anthony can fold 7 towels in 20 minutes. If they all fold towels together, how many towels can they fold in one hour?
A:
There are 1 x 60 minutes = 60 minutes in 1 hour. There are 60 / 5 = 12 sets of 5 minutes in 1 hour. So, Jane can fold 3 x 12 = 36 towels in an hour. There are 60 / 10 = 6 sets of 10 minutes in 1 hour. So, Kyla can fold 5 x 6 = 30 towels in an hour. There are 60 / 20 = 3 sets of 20 minutes in 1 hour. So, Anthony can fold 7 x 3 = 21 towels in an hour. Therefore, the 3 of them can fold a total of 36 + 30 + 21 = 87 towels in 1 hour. The answer is 87.
