They are making 24 S'mores because 8 x 3 = 24. Each S'more costs $.75 to make because 3 / 4 = .75. It will cost $18 to make them all because 24 x .75 = 18.
The answer: 18
Reverse engineering the question: Pat is buying supplies for S'mores. He and his friends will each eat 3 S'mores. There are 8 of them in total. It costs $3 in supplies to make 4 S'mores. How much will it cost to buy all the supplies?


Reasoning and answer: For the hotel Maria paid 300 / 2 = $150. So Maria has 760 - 300 - 150 = $310 left.
The answer: 310
What was the question?
Question: Maria went on a trip to Belgium. She paid $300 for the ticket and half of that for the hotel. How much money does she have left, when she had $760 at the beginning?


The cost for making one birdhouse is $1.50 x 7 = $10.50. So the selling price of one birdhouse is $10.50 + $5.50 = $16. Thus, Denver will charge Danny $16 x 2 = $32 for the two birdhouses.
The answer: 32
Reverse engineering the question: Denver uses 7 pieces of wood for each birdhouse and he pays $1.50 for each piece of wood. If he makes a $5.50 profit per birdhouse, how much will Denver charge to Danny for buying two birdhouses?


Reasoning and answer: First find the total number of basil leaves: 3 pots * 4 leaves / pot = 12 leaves. Then find the total number of rosemary leaves: 9 pots * 18 leaves / pot = 162 leaves. Then find the total number of thyme leaves: 6 pots * 30 leaves / pot = 180 leaves. Then add the number of each type of leaf to find the total number of leaves: 12 leaves + 162 leaves + 180 leaves = 354 leaves.
The answer: 354
What was the question?
Question: Annie plants 3 pots of basil, 9 pots of rosemary, and 6 pots of thyme. Each basil plant has 4 leaves, each rosemary plant has 18 leaves, and each thyme plant has 30 leaves. How many leaves are there total?


First find the cost per member of the hardcover books: $30 / book * 6 books = $180. Then find the cost per member of the paperback books: $12 / book * 6 books = $72. Then find the total cost per member: $180 + $72 + $150 = $402 / member. Now find the total amount of money by multiplying the cost per member by the number of members: $402 / member * 6 members = $2412.
The answer: 2412
Reverse engineering the question: Niles is collecting his book club's annual fees. Each of the six members pays $150/year towards snacks, plus $30 each for six hardcover books and $12 each for six paperback books. How much money does Niles collect in total?


First find how many degrees below 32 the temperature is: 32 degrees - 8 degrees = 24 degrees. Then divide that amount by the number of degrees per 5% increase in skid risk to find how many 5% increases there are: 24 degrees / 3 degrees / 5% increase = 8 5% increases. Multiply the number of increases by 5% to find the total increase in skid risk: 8 * 5% = 40%. Now find the chance that Annie has a serious accident if she goes into a skid by subtracting the chance she regains control from 100%: 100% - 40% = 60%. Finally, multiply the chance of going into a skid by the chance of having a serious accident after a skid to find the total risk of a serious accident: 60% * 40% = 24%.
The answer: 24
Reverse engineering the question:
Annie is trying to figure out whether it's safe to drive her truck. For every 3 degrees the temperature drops below 32 degrees, Annie's chances of skidding on ice increase 5%. If she goes into a skid, she has a 40% of regaining control. Otherwise, she'll have a serious accident. If the temperature is 8 degrees, what is the percentage chance of Annie getting into a serious accident if she drives?
