Monday:70. Tuesday:70 / 2 = 35. Wednesday:35 + 8 = 43. Total:70 + 35 + 43 = 148 birds.
The answer: 148
Reverse engineering the question: A bird watcher records the number of birds he sees each day. One Monday he sees 70 birds. On Tuesday he sees half as many birds as he did on Monday. On Wednesday he sees 8 more birds than he did on Tuesday. How many total birds did the bird watcher see from Monday to Wednesday?


Reasoning and answer: Let c be the amount of time the butterfly spends in a cocoon and l be the amount of time it spends as a larva. We know that l = 3c and l + c = 120. Substituting the first equation into the second equation, we get 3c + c = 120. Combining like terms, we get 4c = 120. Dividing both sides by 4, we get c = 30.
The answer: 30
What was the question?
Question: It takes a butterfly egg 120 days to become a butterfly. If each butterfly spends 3 times as much time as a larva as in a cocoon, how long does each butterfly spend in a cocoon?


The cost of the baguettes is 2 × $2 = $4. The cost of the water is 2 × $1 = $2. The total cost of the shopping is $4 + $2 = $6. Kenneth has $50 − $6 = $44 left.
The answer: 44
Reverse engineering the question: Kenneth has $50 to go to the store. Kenneth bought 2 baguettes and 2 bottles of water. Each baguette cost $2 and each bottle of water cost $1. How much money does Kenneth have left?


Reasoning and answer: The pet store sells the geckos for 5 + 3(100) = 305$. Pet store profit: 305 - 100 = 205$.
The answer: 205

Question: Brandon sold some geckos to a local pet shop. Brandon sold the geckos for 100$. The pet store sells them for 5 more than 3 times that. How much does the pet store profit?


In the second year, the tree will grow 2 x 1.5 = 3 feet. In the third year, it will grow 3 x 1.5 = 4.5 feet. In the fourth year, it will grow 4.5 x 2 = 9 feet. In the fifth year, it will grow 9 / 2 = 4.5 feet. When the tree is 5 years old, including the first year's growth, it will be this tall 2 + 3 + 4.5 + 9 + 4.5 = 23 feet.
The answer: 23
Reverse engineering the question: A papaya tree will grow 2 feet in the first year. In the second year, it will grow 50% more than the first year. In the third year, the tree will grow 50% more than in the second year. In the fourth year, it will grow twice as much as the third year. In the fifth year, it will grow half as much as the fourth year. When the tree is 5 years old, how tall is the tree?


She uses $3.00 of ingredients per 1 bag of granola and she makes 20 bags so she spends 3 * 20 = $60.00 on ingredients. She sells 15 bags for $6.00 so she makes 15 * 6 = $90.00. She sells her last 5 bags for $4.00 so she makes 5 * 4 = $20.00. She made $90.00 and $20.00 for a total of 90 + 20 = $110.00. She made $110.00 but spent $60.00 on ingredients so her net profit is 110 - 60 = $50.00.
The answer: 50
Reverse engineering the question:
Elizabeth uses $3.00 worth of ingredients to make a bag of granola. She makes 20 bags and sells them for $6.00 a bag at the farmer's market. An hour before closing, she has sold 15 bags and marks the remaining 5 bags down to $4.00 and sells them soon after. What is her net profit?
