[Question]Jack collects all his neighbors' recycling and sorts out the cans and bottles to return for the deposit. He gets 10 cents per bottle and 5 cents per can. If he recycled 80 bottles and made $15, how many cans did he recycle?
[Answer]First find the total amount Jack earned from the bottles: $0.10 / bottle * 80 bottles = $8.00. Then subtract that amount from his total earnings to find the amount he earned from cans: $15.00 - $8.00 = $7.00. Then divide his total earnings from cans by his earnings per can to find the number of cans he recycled: $7.00 / $0.05 / can = 140 cans. The answer is 140.
Q: Tommy is making steaks for his family. There are 5 of them in total. If each member wants one pound and the steaks are 20 ounces each, how many does he need to buy?

Question: A baker is comparing the day’s sales to his daily average. He usually sells 20 pastries and 10 loaves of bread. Today, he sells 14 pastries and 25 loaves of bread. If pastries are sold for $2 and loaves of bread are sold for $4, what is the difference, in dollars, between the baker’s daily average and total for today?
Answer: The daily average sales of pastries amounts to 20 pastries * $2 / pastry = $40. The daily average sales of bread amounts to 10 loaves of bread * $4 / loaf = $40. Therefore, the daily average is $40 + $40 = $80. Today’s sales of pastries amounts to 14 pastries * $2 / pastry = $28. Today’s sales of loaves of bread amounts to 25 loaves of bread * $4 / loaf = $100. Therefore, today’s sales amount to $28 + $100 = $128. This means the total difference between today’s sales and the daily average is $128 – $80 = $48. The answer is 48.
[Question]Matilda has half as many jellybeans as Matt. Matt has ten times as many jellybeans as Steve. If Steve has 84 jellybeans, how many jellybeans does Matilda have?

Q: A farmer is checking his fields to make sure all of his crops are growing as they should. Rows of corn stalks should produce 9 corn cobs each, and rows of potatoes should produce 30 potatoes each. As he’s checking crop quality, he notices that there are more pests than usual and they have destroyed some of his crops. He thinks that half of his crops have been destroyed by the pests. If the farmer has 10 rows of corn stalks and 5 rows of potatoes, how many crops does the farmer still have?
A: The farmer had a total of 10 rows of corn stalks * 9 corn cobs each = 90 corn cobs. He also had a total of 5 rows of potatoes * 30 potatoes each = 150 potatoes. This was a total of 90 corn cobs + 150 potatoes = 240 crops. Because pests destroyed half of his crops, he now has 240 crops * 0.5 = 120 crops. The answer is 120.
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.
