Reasoning and answer: He got money from 20 / 2 = 10 households per day. So that means he got money from 10 * 5 = 50 households. Each of those houses gave 20 * 2 = $40. So he raised 40 * 50 = $2000.
The answer: 2000

Question: Mark collects money for the homeless. He visits 20 households a day for 5 days and half of those households give him a pair of 20s. How much did he collect?


The houses are 249 feet in total because 70 + 80 + 99 = 249. The average height is 83 feet because 249 / 3 = 83. Her house is 3 feet shorter because 83 - 80 = 3.
The answer: 3
Reverse engineering the question: Lucille is wondering who has the tallest house between her and her neighbors. His family's house is 80 feet tall. One neighbor's house is 70 feet tall. Another neighbor's house is 99 feet tall. How much shorter is Lucille's house than the average height?


Reasoning and answer: Kyro owes Fernanda half of what Aryan owes Fernanda, a total of 1 / 2 * $1200 = $600. Aryan pays 60% of her dept, which equals 60 / 100 * 1200 = $720. If Fernanda adds the amount she's been paid by Aryan to her savings account, it increases to $300 + $720 = $1020. Kyro also pays her debt by 80 / 100 * $600 = $480. When Fernanda adds the amount she's been paid by Kyro to her savings account, the total amount of money in the savings account increases to $1020 + $480 = $1500.
The answer: 1500

Question: Aryan owes Fernanda $1200, which is twice what Kyro owes Fernanda. Aryan decides to pay 60% of her debt to Fernanda, and Kyro pays Fernanda 80% of her dept. If Fernanda had $300 in her savings account and adds the money she's been paid by her debtors to the savings account, calculate the total amount of money in her savings account now.


Hanna can buy $300 / $2 = 150 roses. So, Jenna will receive 1 / 3 x 150 = 50 roses. While Imma will receive 1 / 2 x 150 = 75 roses. Therefore, Hanna gives a total of 50 + 75 = 125 roses to her friends.
The answer: 125
Reverse engineering the question: Hanna has $300. She wants to buy roses at $2 each and give some of the roses to her friends, Jenna and Imma. Jenna will receive 1/3 of the roses, and Imma will receive 1/2 of the roses. How many roses does Hanna give to her friends?


Reasoning and answer: First add the time spent waiting for the first bus to the time spent on it: 12 minutes + 30 minutes = 42 minutes. Then divide that time by 2 to find the time she spends on the second bus: 42 minutes / 2 = 21 minutes.
The answer: 21

Question: To get to the library, Jill spends 12 minutes waiting for her first bus, 30 minutes riding on her first bus, and half the combined wait and trip time on her second bus. How many minutes does her second bus ride take?


Reasoning and answer: Sabrina had 20 - 10 = 10 cookies left after giving 10 cookies to her brother. Sabrina's mother gave her 10 / 2 = 5 cookies. So, she had 10 + 5 = 15 cookies then. She gave 15 x 2 / 3 = 10 cookies to her sister. Therefore, she only has 15 - 10 = 5 cookies left.
The answer: 5
What was the question?
Question:
Sabrina gave 10 cookies to her brother. Her mother gave Sabrina half the number of cookies she gave her brother. Then Sabrina gave two-thirds of her cookies to her sister. If Sabrina had 20 cookies at the start, how many cookies are left with her?
