Q: It costs $.10 to print one page. Jenny wants to print 7 copies of her 25-page essay. She also wants to buy 7 pens that each cost $1.50. If she pays the store with 2 twenty dollar bills, how much money should she get in change?
A: Jenny needs to print 7 * 25 = 175 pages. This will cost 175 * $.10 = $17.5. The pens will cost 7 * $1.50 = $10.50. In total, she will spend $17.5 + $10.5 = $28. Since she pays with 2 twenty dollar bills she pays with 2 * 20 = 40 dollars. Thus, she will get $40 - $28 = $12 in change. The answer is 12.
Question: A lot of people have been sick at Gary's workplace, so he's been working a lot of extra shifts to fill in for people. As a result, he's earned some overtime (where every hour after 40 he earns 1.5 times his normal wage.) His paycheck (before taxes are taken out) came out to $696. If Gary normally earns $12 per hour, how many hours did he work that week?
Answer: Gary earned overtime, so he worked at least 40 hours. for which he was paid 40 hours * $12 / hour = $480 at his normal wage. This means that $696 - $480 = $216 was earned at his overtime wage. His overtime wage is 1.5 his normal wage, or $12 * 1.5 = $18 per hour. So Gary worked $216 / $18 per hour = 12 hours' worth of overtime. So in total, Gary worked 40 hours + 12 hours = 52 hours that week. The answer is 52.
[Question]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.
[Answer]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.
Q: Sue works in a factory and every 30 minutes, a machine she oversees produces 30 cans of soda. How many cans of soda can one machine produce in 8 hours?
A: Since there are 2 sets of 30 minutes in an hour, then in 8 hours there are 8 x 2 = 16 sets of 30 minutes. Hence, a machine that Sue oversees can produce 30 cans x 16 = 480 cans of soda in 8 hours. The answer is 480.
Question: Peyton has 3 children and they each get a juice box in their lunch, 5 days a week. The school year is 25 weeks long. How many juices boxes will she need for the entire school year for all of her children?
Answer: Each of the 3 children gets 1 juice box, 5 days a week, so she needs 3 * 5 = 15 juice boxes in 1 week. The school year is 25 weeks long and she needs 15 juice boxes per week so she needs 25 * 15 = 375 juice boxes. The answer is 375.
Q: Tina made a large pan of brownies and cut it into 24 pieces. She had one with lunch and dinner every day for 5 days. Her husband snagged one per day for 5 days to take to work. They shared 4 with dinner guests. How many brownies were left?
A:
Tina ate one twice a day for 5 days so 2 * 5 = 10. Her husband at 1 per day for 5 days so 1 * 5 = 5. She made 24, ate 10, her husband ate 5 and the guests ate 4 so 24 - 10 - 5 - 4 = 5 brownies left. The answer is 5.
