[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?
[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 is 30.
Q: 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?
A: 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 is 44.

[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?
[Answer]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 is 23.
[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?
[Answer]
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 is 50.
