Question: A child is making a 5-level pyramid by stacking some blocks. In the first row, he has 9 blocks. For the next rows, he has 2 less than the blocks he has from its bottom row. How many blocks did he use in all?
Answer: On the second row, he used 9 - 2 = 7 blocks. On the third row, he used 7 - 2 = 5 blocks. On the fourth row, he used 5 - 2 = 3 blocks. On the fifth row, he used 3 - 2 = 1 block. Therefore, he used a total of 9 + 7 + 5 + 3 + 1 = 25 blocks. The answer is 25.
[Question]John and James decided to have a dance-off. John danced for 3 hours and then another 5 hours after taking a 1-hour break. James danced the whole time John was dancing and resting, and then another 1/3 times more hours. How long was their combined dancing time without including John's break time?
[Answer]John dances 3 + 5 = 8 hours. John's total time is 3 + 5 + 1 = 9 hours. James dances 9 / 3 = 3 hours longer than that. So James dances 9 + 3 = 12 hours. So the total dancing time is 8 + 12 = 20 hours. The answer is 20.
Q: A cookfire burns three logs every hour. It was built with six logs to start. If it gets two more logs added to it at the end of every hour, how many logs will be left after 3 hours?
A: After 3 hours, it will have 3 * 2 = 6 logs added to it. After 3 hours, it will have burned 3 * 3 = 9 logs. After 3 hours, the cookfire will have 6 + 6 - 9 = 3 logs left. The answer is 3.
Question: Avery puts 4 shirts in the donation box. He adds twice as many pants as shirts in the box. He throws in half as many shorts as pants in the box. In total, how many pieces of clothes is Avery donating?
Answer: The total number of shirts in the donation box is 4. The total number of pants in the donation box is 4 x 2 = 8. The total number of shorts in the donation box is 8 / 2 = 4. The total number of clothes donated is 4 + 8 + 4 = 16 pieces. The answer is 16.
[Question]From Sunday to Thursday, Prudence sleeps 6 hours a night. Friday and Saturday she sleeps for 9 hours a night. She also takes a 1-hour nap on Saturday and Sunday. How much sleep does she get in 4 weeks?
[Answer]5 nights a week she sleeps for 6 hours so she sleeps 5 * 6 = 30 hours. 2 nights a week she sleeps for 9 hours so she sleeps 2 * 9 = 18 hours. 2 days a week she naps for 1 hour so she sleeps 2 * 1 = 2 hours. Over 1 week she sleeps 30 + 18 + 2 = 50 hours. Over 4 weeks she sleeps 4 * 50 = 200 hours. The answer is 200.
[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.
