Monika spent 24 * 3 = 72 dollars at the movies. Monika spent 20 * 1.25 = 25 dollars at the farmers market. Throughout her day, Monika spent 250 + 72 + 25 = 347 dollars.
The answer: 347
Reverse engineering the question: Monika went out for the day and spent some money. She went to the mall and spent $250. Then, she went to the movies and watched 3 movies back to back that each cost $24. Then she stopped by the farmer's market on her way home and got 20 bags of beans at $1.25/bag. How much money did Monika spend throughout her day?
Reasoning and answer: At the end of 2018, the tree will grow 100 x 10 / 100 = 10 meters more. Thus, its height at the end of 2018 is 100 + 10 = 110 meters. At the end of 2019, the tree will grow 110 x 10 / 100 = 11 meters more. So, its height at the end of 2019 is 110 + 11 = 121 meters. Therefore, the tree has grown 121 - 100 = 21 meters.
The answer: 21
What was the question?
Question: A certain tree was 100 meters tall at the end of 2017. It will grow 10% more than its previous height each year. How long has the tree grown from 2017 until the end of 2019?
If Roselyn gave Rebecca 40 books, and Mara was given three times as many books, Mara has 3 * 40 = 120 books. Rebecca and Mara's total number of books is 120 + 40 = 160 books. If Roselyn gave Mara and Rebecca her books, which is 160, then she initially had 60 + 160 = 220 books.
The answer: 220
Reverse engineering the question: Roselyn gives Mara three times as many books as she gives Rebecca and remains with 60 books. If Rebecca received 40 books, how many books did Roselyn have before?
Reasoning and answer: A small knife is twice the amount of the utensils that costs $10.00 so the knife costs 2 * 10 = $20.00. All total, each little kit will costs $14.00 for mitts, $16.00 for an apron, $10.00 for utensils and $20.00 for a knife for a total of 14 + 16 + 10 + 20 = $60.00. Each kit costs $60.00 and they are currently 25% off so that's a savings of 60 * .25 = $15.00. The kits are $60.00 and they are $15.00 off so they now cost 60 - 15 = $45.00. She needs to buy 3 kits and each kit costs $45.00 so that's 3 * 45 = $135.00.
The answer: 135

Question: Eve wants to buy her 3 nieces cooking gear that's made for kids. The hand mitts cost $14.00 and the apron is $16.00. A set of 3 cooking utensils is $10.00 and a small knife is twice the amount of the utensils. The store is offering a 25% off sale on all cooking gear. How much will Eve spend on the gifts?
The tree has been planted for 9 - 4 = 5 years. It will take another 7 - 5 = 2 years for it to bear fruit. Lydia will be 9 + 2 = 11 years old.
The answer: 11
Reverse engineering the question: It takes 7 years for an apple tree to bear fruit. If Lydia planted a tree when she was 4 years old and is now 9 years old, how old would she be when she gets to eat an apple from her tree for the first time?
The bag is now sold for $150 - $135 = $15 less. The discount is 15 / 150 = 1 / 10. Thus, the percent discount is 1 / 10 x 100% = 10%.
The answer: 10
Reverse engineering the question:
While passing by a store, Miley noticed that a bag that cost $150 last week is now on sale for $135. What percent is the discount?
