Twice what Orlando gained is 2 * 5 = 10 pounds. Jose gained two pounds more than twice what Orlando gained for a total of 2 + 10 = 12 pounds.. Half of what Jose gained is 12 / 2 = 6 pounds. Fernando gained 3 pounds less than half of what Jose gained, for a total of 6 - 3 = 3 pounds. In total, the three family members gained 5 + 12 + 3 = 20 pounds at the reunion.
The answer: 20
Reverse engineering the question: At the family reunion, everyone ate too much food and gained weight. Orlando gained 5 pounds. Jose gained two pounds more than twice what Orlando gained. Fernando gained 3 pounds less than half of what Jose gained. How much weight, in pounds, did the three family members gain at their reunion?


Reasoning and answer: If Debby's share is 25% and Maggie takes the rest, then Maggie's share is 100% - 25% = 75%. 75% of the total amount is Maggie's share = total amount * (75 / 100) = $4500. Multiplying both sides of the equation by 100 / 75 gives the total amount = (100 / 75) * $4500 = $6000.
The answer: 6000
What was the question?
Question: Debby and Maggie agreed to share a sum of money so that Debby takes 25% and Maggie takes the rest. If Maggie's share is $4,500, how much did they share?


In the large orders, Lisa used 3 large orders * 200g of packing peanuts per large order = 600g of packing peanuts. The rest of the packing peanuts were used in small orders so there was a total of 800g packing peanuts - 600g of packing peanuts used in large orders = 200g of packing peanuts used in small orders. So there must have been 200g of packing peanuts / 50g of packing peanuts per small order = 4 small orders.
The answer: 4
Reverse engineering the question: Vanessa's new business is thriving and she frequently has orders to post. She has run out of packing peanuts for the packages and is now wondering how many orders she has sent. Each large order needs 200g of packing peanuts while small orders need just 50g of packing peanuts. If Lisa has used a total of 800g of packing peanuts and she knows she has sent 3 large orders, how many small orders has Lisa sent?


Reasoning and answer: On Tuesday she sells 5 crates * 2 = 10 crates of eggs. On Wednesday she sells 10 crates - 2 crates = 8 crates of eggs. On Thursday she sells 1 / 2 * 10 crates = 5 crates of eggs. She sells a total of 5 crates + 10 crates + 8 crates + 5 crates = 28 crates of eggs.
The answer: 28
What was the question?
Question: Gabrielle sells eggs. On Monday she sells 5 crates of eggs. On Tuesday she sells 2 times as many crates of eggs as Monday. On Wednesday she sells 2 fewer crates than Tuesday. On Thursday she sells half as many crates of eggs as she sells on Tuesday. How many total crates of eggs does she sell for the 4 days?


Lionel has enough Graham crackers to make 14 / 2 = 7 Oreo cheesecakes. Lionel has enough Oreos to make 15 / 3 = 5 Oreo cheesecakes. Therefore, the maximum number of cheesecakes Lionel can make is 5. Lionel needs 2 * 5 = 10 boxes of Graham crackers to make 4 cheesecakes. He'll have 14 - 10 = 4 boxes left over.
The answer: 4
Reverse engineering the question: Lionel went to the grocery store and bought 14 boxes of Graham crackers and 15 packets of Oreos. To make an Oreo cheesecake, Lionel needs 2 boxes of Graham crackers and 3 packets of Oreos. After making the maximum number of Oreo cheesecakes he can with the ingredients he bought, how many boxes of Graham crackers would he have left over?


Since 80% of the people were adults, this means 100% - 80% = 20 % were children. 20% of the people vaccinated were children. The number of children is 20% of 650. 20% = 0.2, so 0.2 * 650 = 130 children were vaccinated.
The answer: 130
Reverse engineering the question:
A clinic administered the covid vaccine to 650 people. 80% of the people were adults. How many of the vaccinated people were children?
