From the 200 cookies, Javier's wife ate 30 / 100 * 200 = 60. After the wife ate 60 cookies, the number of cookies that remained was 200 - 60 = 140. The daughter also ate 40 cookies leaving 140 - 40 = 100 cookies. If Javier ate half of the remaining cookies, he ate 1 / 2 * 100 = 50. The number of cookies that remained is 100 - 50 = 50.
The answer: 50
Reverse engineering the question: Out of the 200 cookies that Javier baked from the recipe he learned online, his wife took 30%, and his daughter took 40 from the remaining cookies. If he ate half of the remaining cookies, how many cookies did they not eat?


Reasoning and answer: First = 14 oz. Second = (1 / 2) * 14 = 7 oz. Third = 7 + 5 = 12 oz. 14 + 7 + 12 = 33 oz. There are 33 ounces of cereal in those 3 boxes.
The answer: 33
What was the question?
Question: There are 3 boxes of cereal. One box holds 14 ounces of cereal. Another box holds half the amount of the first box and 5 ounces less than the third box. How much cereal is there in all 3 cereal boxes?


During each boat trip, there can be 12 people onboard, so during 4 boat trips, there can be 4 * 12 = 48 people in total. During two days the boat can transport a total of 48 * 2 = 96 people.
The answer: 96
Reverse engineering the question: During one day, there are 4 boat trips through the lake. The boat can take up to 12 people during one trip. How many people can the boat transport in 2 days?


Reasoning and answer: There are 26 total desserts because 14 plus 12 equals 26. Each student gets 2 desserts because 26 divided by 13 equals 2.
The answer: 2
What was the question?
Question: The teacher brings in 14 mini-cupcakes and 12 donut holes for the class. There are 13 students in the class. If each student gets the exact same amount, how many desserts does each student get?


First, we need to determine the profit per book. To do this, we perform 20 - 5 = 15 dollars in profit per book. Next, we divide the total sales by the profit per book, performing 120 / 15 = 8 books sold in total. Since the books are sold 2 at a time, we divide the number sold by 2 to find the total number of people sold to, performing 8 / 2 = 4 people in total.
The answer: 4
Reverse engineering the question: Tina is getting $20 for each book she sells. If she realizes a $120 profit on her sales, how many people have she sold the books to if each book costs $5 to make and every customer buys 2 at a time?


First find the total number of starfish arms: 7 starfish * 5 arms / starfish = 35 arms. Then add the number of seastar arms to find the total number of arms: 35 arms + 14 arms = 49 arms.
The answer: 49
Reverse engineering the question:
Carly collected 7 starfish with 5 arms each and one seastar with 14 arms. How many arms do the animals she collected have in total?
