Reasoning and answer: She starts with $5.00 a week for 4 weeks so that's 5 * 4 = $20.00. Then she bumps it up to $10.00 a week for 4 weeks so that's 10 * 4 = $40.00. After that, she saves $20.00 a week for 4 weeks so that's 20 * 4 = $80.00. Over 12 weeks she has saved 20 + 40 + 80 = $140.00.
The answer: 140

Question: Sarah starts saving $5.00 a week for 4 weeks. Then she saves $10.00 a week for the next 4 weeks. Then she saves $20.00 a week for the next 4 weeks. How much money has she saved over 12 weeks?
If Ollie caught 7 less than Angus, then Angus caught 5 + 7 = 12 fish. And since Angus caught four more than Patrick, then Patrick caught 12 - 4 = 8 fish.
The answer: 8
Reverse engineering the question: Angus, Patrick, and Ollie went fishing for trout on Rainbow Lake. Angus caught 4 more fish than Patrick did, but Ollie caught 7 fewer fish than Angus. If Ollie caught 5 fish, how many fish did Patrick catch?
Reasoning and answer: In 7 years, Kaylee will be 5 * 3 = 15 years old. Let x be the age Kaylee is now. After 7 years, Kaylle will be 15 years old, so x + 7 = 15. x = 15 - 7. x = 8 years old.
The answer: 8

Question: In 7 years, Kaylee will be 3 times as old as Matt is now. If Matt is currently 5 years old, how old is Kaylee now?
If the total cost of an orange and a pear is $120, and a pear costs $90, an orange costs $120 - $90 = $30. Since the difference between the price of an orange and a pear is the price of a banana, a banana is sold at $90 - $30 = $60. To buy 200 bananas, you'll pay $60 * 200 = $12000. When you twice as many oranges as bananas, you buy 2 * 200 = 400 oranges. The total cost of buying 400 oranges is 400 * 30 = $12000. The total price of buying 200 bananas and twice as many oranges as bananas is $12000 + $12000 = $24000.
The answer: 24000
Reverse engineering the question: The difference between the price of an orange and the price of a pear equals the price of a banana. If the total cost of an orange and a pear is $120 and a pear costs $90, calculate the total price of buying 200 bananas and twice as many oranges as bananas.
Reasoning and answer: Orlan gave Allan 20 x 1 / 4 = 5 meters of rope. So he had 20 - 5 = 15 meters left. Then he gave 15 x 2 / 3 = 10 meters of the rope to Jack. Therefore, Orlan is left with 15 - 10 = 5 meters of rope.
The answer: 5
What was the question?
Question: Orlan gave one-fourth of his 20-meter rope to Allan. He then gave two-thirds of the remaining to Jack. How many meters of rope is left to Orlan?
Reasoning and answer: After giving $5, Lucy has $20 - $5 = $15 left. Since Linda has $15 after receiving $5, then she had $15 - $5 = $10 at the beginning.
The answer: 10
What was the question?
Question:
If Lucy would give Linda $5, Lucy would have the same amount of money as Linda. If Lucy originally had $20, how much money did Linda have at the beginning?
