[Question]Catherine had an equal number of pencils and pens. If she had 60 pens and gave eight pens and 6 pencils to each of her seven friends and kept the rest for herself, how many pens and pencils did she have left?
[Answer]Catherine gave eight pens to each of her seven friends, a total of 8 * 7 = 56 pens. She remained with 60 - 56 = 4 pens. When she also gave 6 pencils to each of her seven friends, she gave away 6 * 7 = 42 pencils. Since she had the same number of pencils as pens, she remained with 60 - 42 = 18 pencils. The total number of pens and pencils that Catherine remained with is 4 + 18 = 22. The answer is 22.
Q: Irene earns $500 if she works for 40 hours a week and gets an extra $20 for every hour of overtime. If she worked 50 hours last week, calculate her total income.
A: If Irene worked 50 hours last week, the total number of hours counting as overtime is 50 - 40 = 10 hours. Since she's given $20 for every hour of overtime, she earned 10 * $20 = $200 in overtime. Her total income, including the overtime, is $500 + $200 = $700. The answer is 700.
Question: It's Ava's birthday party. Her parents bought a unicorn pinata for $13 and filled it with all of her favorite treats. They bought 4 bags of Reese's for $9 per bag, 3 bags of Snickers for $5 per bag, and 5 bags of Skittles for $7 per bag. How much did the unicorn pinata and the treats cost altogether?
Answer: The four bags of Reese's cost $9 x 4 = $36. The three bags of Snickers cost $5 x 3 = $15. The five bags of Skittles cost $7 x 5 = $35. Therefore, the unicorn pinata and the treats cost $13 + $36 + $15 + $35 = $99. The answer is 99.
[Question]Oliver wonders how much water his bathtub can hold. So he takes a bucket that holds 120 ounces and starts filling the bathtub. When it reaches the top, he sees that he filled it 14 times. Then he wonders how much bathwater he uses, so he starts taking away buckets until it gets to the level he puts it at. He needs to take away 3 buckets to do this. Finally, he wonders how much water he uses in a week for his baths, which he takes every day. How much water does he use each week?
[Answer]He uses 11 buckets to fill his bath normally because 14 - 3 = 11. He uses 1, 320 ounces a day for his baths because 11 x 120 = 1,320. He uses 9, 240 ounces a week for his baths because 7 x 1,320 = 9,240. The answer is 9240.
Q: You start a business selling charm bracelets. You spend $1 on the string for each bracelet and $3 on beads for each bracelet. You sell the bracelets for $6 each. If you sell 25 bracelets, how much profit will you make?
A: It costs $1 + $3 = $4 to make each bracelet. Your total cost is 25 * $4 = $100. Total revenue is 25 * $6 = $150. Total profit is $150 - $100 = $50. The answer is 50.
Question: An avant-garde sushi house sells jellyfish for a certain amount and eel for nine times that amount. If the combined cost of one order each kind of sushi is $200, how much does the eel cost?
Answer:
Let j be the cost of the jellyfish and e be the cost of the eel. We know that j + e = $200 and e = 9j. Substituting the second equation into the first equation, we get j + 9j = $200. Combining like terms, we get 10j = $200. Dividing both sides by 10, we get j = $20. Substituting this value back into e = 9j, we get e = 9 * $20 = $180. The answer is 180.
