[Question]Three cats sat on a fence, meowing at the moon. The first cat meowed 3 times per minute. The second cat meowed twice as frequently as the first cat. And the third cat meowed at one-third the frequency of the second cat. What is the combined total number of meows the three cats make in 5 minutes?
[Answer]The second cat meowed twice as frequently as the three meows per minute from the first cat, for a total of 2 * 3 = 6 meows per minute. The third cat meowed at one - third the frequency of the second cat, for a total of 6 / 3 = 2 meows per minute. Thus, combined, the three cats meow 3 + 6 + 2 = 11 times per minute. In five minutes, the three cats meow 5 * 11 = 55 times. The answer is 55.
Q: The electricity price in Coco's town is $0.10 per kW. Coco's new oven has a consumption rate of 2.4 kWh (kilowatt-hours). How much will Coco pay for using his oven only if he used it for a total of 25 hours last month?
A: If Coco used his oven 25 hours last month and its energy consumption is 2.4 kW per hour, then we consumed a total of 25 * 2.4 = 60 kW on his oven last month. If the price of electricity is $0.10 per kW, then 60 kW would cost = $0.10 * 60 = $6. The answer is 6.
Question: An 18-month magazine subscription is normally $34. The magazine is currently running a promotion for $0.25 off each twice-a-month issue when signing up for the 18-month subscription. How many dollars cheaper is the promotional subscription than the normal one?
Answer: The subscription sends twice monthly issues, so there are 2 * 18 = 36 issues. Thus, the promotional offer is 36 * 0.25 = $9 cheaper than the normal subscription. The answer is 9.
[Question]Tom wants to make the world's largest dough ball. He needs 500 pounds of flour and he can buy 50-pound bags of flour for $20. He also needs 10 pounds of salt and salt cost $.2 a pound. He also spends $1000 promoting everything. He then sells tickets for $20 each and sells 500 tickets. How much money did he make?
[Answer]He needs 500 / 50 = 10 bags of flour. That cost 20 * 10 = $200. He needs 10 * .2 = $2 worth of salt. So everything cost 1000 + 200 + 2 = $1202. He makes 20 * 500 = $10,000 selling tickets. So he makes a profit of 10000 - 1202 = $8798. The answer is 8798.

Question: Bill is trying to decide whether to make blueberry muffins or raspberry muffins. Blueberries cost $5.00 per 6 ounce carton and raspberries cost $3.00 per 8 ounce carton. If Bill is going to make 4 batches of muffins, and each batch takes 12 ounces of fruit, how much money would he save by using raspberries instead of blueberries?
Answer:
First find how many ounces of fruit Bill will need total: 12 ounces / batch * 4 batches = 48 ounces. Then find how many cartons of blueberries Bill would need: 48 ounces / 6 ounces / carton = 8 cartons. Then multiply that number by the cost per carton to find the total cost of the blueberries: 8 cartons * $5 / carton = $40. Then find how many cartons of raspberries Bill would need: 48 ounces / 8 ounces / carton = 6 cartons. Then multiply that number by the cost per carton to find the total cost of the raspberries: 6 cartons * $3 / carton = $18. Then subtract the cost of the raspberries from the cost of the blueberries to find the difference: $40 - $18 = $22. The answer is 22.
