First find the total time it takes Maryann to rescue one friend: 6 minutes + 8 minutes = 14 minutes. Then multiply the time to save one friend by the number of friends Maryann needs to save: 14 minutes / friend * 3 friends = 42 minutes.
The answer: 42
Reverse engineering the question: Maryann can pick the lock on a cheap pair of handcuffs in 6 minutes and on an expensive pair of handcuffs in 8 minutes. If Maryann needs to rescue three of her friends who have expensive handcuffs on their hands and cheap handcuffs on their ankles, how long will it take for her to free all of them?


Reasoning and answer: 15% of $80 = (15 / 100) * $80 = $12. The dollar amount of the discount is $12 so he is supposed to pay just $80 - $12 = $68.
The answer: 68

Question: Barry goes to a shop to buy a shirt he'd been admiring for quite some time. He tells the attendant that it's his birthday so she decides to give him a 15% special discount. The price tag on the shirt says $80. How much is he supposed to pay now, considering the special discount?


The checkpoints are 1 mile from the start and finish, so they are spaced along 26 - 1 - 1 = 24 miles. There are 4 equally spaced checkpoints, so the checkpoints are 24 / 4 = 6 miles apart.
The answer: 6
Reverse engineering the question: A 26-mile circular marathon has four checkpoints inside it. The first is one mile from the start line, and the last checkpoint is one mile from the finish line. The checkpoints have equal spacing between them. How many miles apart are each of the consecutive checkpoints between the start-finish line?


Reasoning and answer: First subtract the coupon amount from the price of the food: $7.50 - $2.50 = $5.00. Then subtract 20% from 100% to find out what percentage of the reduced price Carla pays: 100% - 20% = 80%. Now multiply the price after the coupon by the percentage Carla pays to find the final price: $5.00 * .8 = $4.00.
The answer: 4

Question: Carla's order at Mcdonald's costs $7.50, but she has a coupon for $2.50. If she gets an additional 20% discount for being a senior citizen, how much does she pay for her order in dollars total?


He dropped two cantaloupes and had 8 left over at the end of the day, so he sold 30 - 2 - 8 = 20 cantaloupes. Three honeydews were rotten, and he had 9 left at the end of the day, so he sold 27 - 3 - 9 = 15 honeydews. He sold 20 cantaloupes * $2 / cantaloupe = $40 in cantaloupes. He also sold 15 honeydews * $3 / honeydew = $45 in honeydews. Altogether he made $40 + $45 = $85.
The answer: 85
Reverse engineering the question: Darryl sells melons on the side of the road. He sells cantaloupes for $2 each and honeydews for $3. He started the day with 30 cantaloupes and 27 honeydews. He accidentally dropped a couple of cantaloupes and three of the honeydews turned out to be rotten. At the end of the day he had 8 cantaloupes and 9 honeydews left. How much money did he make?


There are 750 / 3 = 250 kids going to soccer camp in the morning. There are 250 * 4 = 1000 kids going to soccer camp altogether. There are 1000 * 2 = 2000 kids in camp altogether.
The answer: 2000
Reverse engineering the question:
There are some kids in camp. Half of the kids are going to soccer camp, and 1/4 of the kids going to soccer camp are going to soccer camp in the morning. 750 kids are going to soccer camp in the afternoon. How many kids there in camp altogether?
