Q: In a studio audience of 100 people, 40% of these people have an envelope taped underneath their chairs. 20% of these people will have "You Won" in their envelope, the rest will have empty envelopes. How many people will win a prize?
A: 40% of the 100 studio audience will have an envelope under their chair so .40 * 100 = 40 people will find an envelope. 20% of these 40 people will find a "You Won" notice so only .20 * 40 = 8 people will win. The answer is 8.
Question: Bob orders a pizza with 8 slices. He eats half of it and each slice was 300 calories. How many calories did he eat?

[Question]James started a food fight in his school's cafeteria, and the school administration is making him work off the cost of all the food he wasted at minimum wage ($8). James has to pay for 20 wasted pounds of meat at $5/pound, 15 wasted pounds of fruits and vegetables at $4/pound, 60 wasted pounds of bread products at $1.50/pound, and 10 hours of time-and-a-half pay for the janitorial staff, who normally make $10/hour. How many hours will James have to work to pay for everything?
[Answer]First find the total cost of the wasted meat: $5 / pound * 20 pounds = $100. Then find the total cost of the wasted vegetables: $4 / pound * 15 pounds = $60. Then find the total cost of the wasted bread products: $1.50 / pound * 60 pounds = $90. Then find the time - and - a - half rate for the janitors: $10 / hour * 1.5 = $15 / hour. Then multiply that by the number of hours to find the total janitorial cost: $15 / hour * 10 hours = $150. Then add up all the costs to find the total cost of everything: $100 + $60 + $90 + $150 = $400. Then divide the total James owes by his hourly wage to find how many hours he needs to work: $400 / $8 / hour = 50 hours. The answer is 50.
Q: Jairus read 20 pages of the newspaper. Arniel read 2 more than twice the number of pages Jairus read. How many pages have they read altogether?
A: Twice the number of pages Jairus read is 20 x 2 = 40. Arniel read 40 + 2 = 42 pages of the newspaper. Jairus and Arniel read 20 + 42 = 62 pages altogether. The answer is 62.
Question: Travis goes through 2 boxes of cereal a week. If each box costs $3.00 and he eats 2 boxes every week for an entire year, 52 weeks, how much does he spend on cereal?
Answer: He eats 2 boxes for 52 weeks so he eats 2 * 52 = 104 boxes. Each box costs $3.00 and he buys 104 boxes so he spends 3 * 104 = $312.00. The answer is 312.
Q: Darren bought 4 boxes of crackers. Each box contained 24 crackers. If Calvin bought one box less than twice as many boxes of crackers as Darren, how many crackers did they buy altogether?
A:
If Darren bought 4 boxes of crackers, each containing 24 crackers, the total number of crackers that Darren bought is 24 * 4 = 96. Twice as many boxes of crackers as Darren bought is 2 * 4 = 8. If Calvin bought one box less than twice as many boxes of crackers as Darren, then Calvin bought 8 - 1 = 7 boxes of crackers. The total number of crackers that Calvin bought is 7 * 24 = 168. Together, Darren and Clavin bought 168 + 96 = 264 crackers. The answer is 264.
