Two pairs of shoes at $50 a pair costs $50 x 2 = $100. The shoes are discounted by 40 percent so she only pays 100 - 40 = 60 percent of the original price. Therefore the two pairs of shoes cost $100 x 0.60 = $60. The dress is discounted by 20 percent so she only pays 100 - 20 = 80 percent of the original price. Therefore the dress costs $100 x 0.80 = $80. In total Daniela spends $60 + $80 = $140 for two pairs of shoes and a dress.
The answer: 140
Reverse engineering the question: Daniela goes shopping during a sale. She finds out that the store has 40 percent off on shoes and 20 percent off dresses. If Daniela buys 2 pairs of shoes originally priced at $50 a pair and a dress originally priced at $100, how much money does she spend?
Reasoning and answer: Since the angles in a triangle adds up to 180, and A is 40 degrees, B and C have a total of 180 - 60 = 120 degrees. Since B is two times bigger than C, the total of the angles of B and C is equal to 2C + C = 120. 3C = 120. The angle of C is C = 120 / 3. C is 40. Since B is two times as big as C, B is 2 * 40 = 80 degrees.
The answer: 80

Question: In a triangle with angles A, B, and C, A is 60 degrees, and B is two times as big as C. Calculate the angle of B.
1 bottle of soap will last for 4 washes and he needs enough bottles for 20 weeks so 20 / 4 = 5 bottles. Each bottle cost $4.00 and he needs 5 bottles so he will spend $4 * 5 = $20.00 on car soap.
The answer: 20
Reverse engineering the question: Jake can wash his car with 1 bottle of car wash soap 4 times. If each bottle costs $4.00, and he washes his car once a week for 20 weeks, how much does he spend on car soap?
Reasoning and answer: The quilt is 144 square feet because 6 x 24 = 144. A square quilt would be 12 feet per side because (144) = 12.
The answer: 12

Question: Tony has a piece of quilt that is 6 feet by 24 feet. If he wants to turn it into a square and use all the fabric, how long is each side of the square?
First find the total revenue from the matinee tickets: $5 / ticket * 200 tickets = $1000. Then find the total revenue from the evening tickets: $12 / ticket * 300 tickets = $3600. Then find the total revenue from the 3D tickets: $20 / ticket * 100 tickets = $2000. Then add the cost of each group of tickets to find the total cost: $1000 + $3600 + $2000 = $6600.
The answer: 6600
Reverse engineering the question: The movie theater sells matinee tickets for $5, evening tickets for $12, and 3D tickets for $20. If they sell 200 matinee tickets, 300 evening tickets and 100 3D tickets, how much money do they make in total?
Mike received 3 oranges. Matt received twice as many apples as Mike received oranges, so he got 3 * 2 = 6 apples. Mark received 6 + 3 = 9 bananas. So in total, all children received 3 + 6 + 9 = 18 fruits.
The answer: 18
Reverse engineering the question:
Annie is a mother of 3 children: Mark, Matt, and Mike. She decided to give them some fruits. Mike received 3 oranges. Matt got twice as many apples, and Mark got as many bananas as Mike and Matt received fruits altogether. How many fruits do the three children have in total?
