Q: Janet makes 50 snowballs and her brother makes 150 snowballs. What percentage of the snowballs did Janet make?
A: First add the number of snowballs each person made to find the total: 50 snowballs + 150 snowballs = 200 snowballs. Then divide the number Janet made by the total number and multiply by 100% to express the answer as a percentage: 50 snowballs / 200 snowballs * 100% = 25%. The answer is 25.
Question: Debra is the host of a country music radio show, and she broadcasts interviews with celebrity country music singers. Each week, she interviews three singers, one at a time. The first interview segment is always twice as long as the other two segments combined, and the third interview segment is always half as long as the second. If the third segment is 10 minutes long, how many minutes long is the entire show?
Answer: If the third segment is half as long as the second, then the second segment is twice as long as the third, or 10 * 2 = 20 minutes long. The first segment is twice as long as the other two combined, or 2 * (10 + 20) = 60 minutes. Thus, in total, the show is 10 + 20 + 60 = 90 minutes long. The answer is 90.

Q: Julie is reading a 120-page book. Yesterday, she was able to read 12 pages and today, she read twice as many pages as yesterday. If she wants to read half of the remaining pages tomorrow, how many pages should she read?
A: Maila read 12 x 2 = 24 pages today. So she was able to read a total of 12 + 24 = 36 pages since yesterday. There are 120 - 36 = 84 pages left to be read. Since she wants to read half of the remaining pages tomorrow, then she should read 84 / 2 = 42 pages. The answer is 42.
Question: Paul earns $12.50 for each hour that he works. He then has to pay 20% for taxes and fees. After working 40 hours, Paul receives his paycheck. If he spends 15% of his paycheck on gummy bears, how much, in dollars, does he have left?
Answer:
His pay before taxes and fees is $12.50 x 40 hours = $500. He pays $500 * 0.20 = $100 for taxes and fees. Then he had $500 - $100 = $400 remaining money. He takes out $400 * 0.15 = $60 for his gummy bears. So he's left with $400 - $60 = $340. The answer is 340.
