So first, we should add the prices of all salons. At Gustran Salon, the total price is: $45 + $22 + $30 = $97. The total price at Barbara's shop is: $40 + $30 + $28 = $98. The total price at The Fancy Salon is: $30 + $34 + $20 = $84. At Gustran salon she would spend $97, at Barbara's Shop she would spend $98, and at The Fancy Salon she would spend $84, so she would spend $84 at the cheapest salon.
The answer: 84
Reverse engineering the question: Haily wants to go to the salon and do her nails, cut her hair and do a facial cleaning. She doesn't want to spend much, so she called 3 salons to get their prices: Gustran Salon, Barbara's Shop, and The Fancy Salon. At Gustran Salon, the haircut is $45, the facial cleaning is $22 and the nails are $30. At Barbara's shop, the nails are $40, the haircut is $30 and the facial cleaning is $28. And, at the Fancy Salon, the facial cleaning is $30, the haircut is $34 and the nails are $20. How much would Haily spend at the cheapest salon?
Reasoning and answer: Wilson had $150 + $17 = $167 two months ago before making a withdrawal. His money in his account now is $150 + $16 = $166. Since he deposited $21 this month, this means there was $166 - $21 = $145 last month after making a withdrawal. Therefore, Wilson withdrew $167 - $145 = $22.
The answer: 22
What was the question?
Question: Two months ago, Wilson had a total of $150 in his bank account. Then last month, he deposited $17. A few days after, he made a withdrawal. This month, he deposited $21 so he has $16 more than what is in his account two months ago. How much did Wilson withdraw last month?
The dinner cost 10 + 2.5 = $12.5. The tip comes to 12.5 * .2 = $2.5. So the total cost is 12.5 + 2.5 = $15. That means she gets 20 - 15 = $5 in change.
The answer: 5
Reverse engineering the question: Kim orders a $10 meal and a drink for 2.5. She gives a 20% tip. She pays with a $20 bill. How much does she get in change?
Reasoning and answer: Jasmine swims 5 days a week. The number of laps per week is 12 laps / day * 5 days / week = 60 laps / week. In five weeks, she swims 5 weeks * 60 laps / week = 300 laps.
The answer: 300
What was the question?
Question: Jasmine swims 12 laps every afternoon, Monday through Friday. How many laps does she swim in five weeks?
In June the hobby store sold 21,122 + 3,922 = 25,044 trading cards. Over June and July the store sold 25,044 + 21,122 = 46,166 trading cards.
The answer: 46166
Reverse engineering the question: The hobby store normally sells 21,122 trading cards per month. In June, the hobby store sold 3,922 more trading cards than normal.

In her hamper, Brie has 12 x 75% = 9 blouses. In her hamper, she has 6 x 50% = 3 skirts. In the hamper, she has 8 x 25% = 2 slacks. She will need to wash 9 + 3 + 2 = 14 pieces of clothes.
The answer: 14
Reverse engineering the question:
