user: He will spend 5 x 2 = 10 hours if he takes route A. Meanwhile, he will spend 2 x 2 = 4 hours if he takes route B. Therefore, Joseph can save 10 - 4 = 6 hours if he takes route B both ways.
The answer: 6
Reverse engineering the question: Joseph wants to go to Boston for a road trip. If he takes route A, it will take him 5 hours to arrive; but if he takes route B, it will only take him 2 hours to arrive at his destination. How much time will he save if he takes route B to Boston and back to his home?
Reasoning and answer: The taxi charge for a distance of 4 miles is 4 x $2.5 = $10. The total amount that Michelle paid for the ride was $2 + $10 = $12.
The answer: 12
What was the question?
Question: As soon as you enter the taxi, you pay a ride fee of $2. Michelle rode a taxi from her office to her home, which constitutes 4 miles. If the taxi charge per mile is $2.5, how much did pay Michelle pay in total for her ride?
There are 7 days in a week and they're going for 2 weeks so that's 7 * 2 = 14 days. The daily rate is $125.00 and they are staying for 14 days so that's 125 * 14 = $1,750.00. There is also a $100.00 pet fee on top of their rental fee of $1,750.00 so that's 100 + 1750 = $1850.00. There is a 20% fee on the $1,850.00 so the fee comes to .20 * 1850 = $370.00. The rental will costs $1,850.00 and there is $370.00 service / cleaning fee for a total of 1850 + 370 = $2,220.00. They need to pay 50% of the entire bill as a security deposit so that will be .5 * 2220 = $1,110.00.
The answer: 1110
Reverse engineering the question: Lana and Mike are taking their dog and renting a cabin in the mountains for 2 weeks. The daily rate is $125.00 There is a $100.00 pet fee. There is also a 20% service/cleaning fee for the rental. They need to pay 50% of the entire bill as a security deposit. How much is their security deposit?
Reasoning and answer: The cost of 9 plates is $2 x 9 = $18. So, Chenny paid $24 - $18 = $6 for the spoons. Therefore, she bought $6 / $1.50 = 4 spoons.
The answer: 4
What was the question?
Question: Chenny bought 9 plates at $2 each. She also bought spoons at $1.50 each. How many spoons did Chenny buy if she paid a total of $24 for the plates and spoon?
On the first day, Lucca ate 1 / 4 * 200 = 50 pieces. The number of pieces remaining after the first day is 200 - 50 = 150. On the second day, Lucca ate 2 / 5 * 150 = 60 pieces of bread. The pieces of bread that remained after the second day is 150 - 60 = 90. If Lucca ate half of the remaining pieces of bread on the third day, he ate 1 / 2 * 90 = 45 pieces. The pieces of bread that are remaining after the third day are 90 - 45 = 45.
The answer: 45
Reverse engineering the question: Lucca bought 200 pieces of bread. Lucca ate 1/4 of the pieces of bread in one day, and 2/5 of the remaining pieces the next day. If he ate half of the remaining pieces on the third day, calculate how many pieces of bread are remaining.
There are 30 / 2 = 15 pictures hanging horizontally. So there is a total of 15 + 5 = 20 pictures hanging either horizontally or haphazardly. Therefore, there are 30 – 20 = 10 pictures hanging vertically.
The answer: 10
Reverse engineering the question:

assistant: Louise is hanging 30 of her pictures on the wall. She hangs some of them vertically, half of them horizontally, then hangs the remaining 5 pictures haphazardly. How many pictures did Louise hang vertically?
