[Question]Mike and Leo have to print as many pamphlets as possible for a social gathering. Mike manages to print as fast as 600 pamphlets per hour for 9 consecutive hours. After a break, he resumes the task for another 2 hours achieving a third of the speed he was doing before. Leo, on the other hand, only works a third as many hours as Mike did before his break, but was twice as fast as Mike before he took his break. How many pamphlets do both manage to print at the end?
[Answer]Mike printed before the break 600 pamphlets per hour * 9 hours = 5400 pamphlets. The working speed of Mike after the break was 600 pamphlets per hour / 3 = 200 pamphlets per hour. Mike printed after the break 200 pamphlets per hour * 2 hours = 400 pamphlets. Leo worked third of the time that Mike worked before the break, so he worked 9 hours / 3 = 3 hours. Leo worked twice as fast as Mike before his break 600 pamphlets per hour * 2 = 1200 pamphlets per hour. Leo printed 1200 pamphlets per hour * 3 hours = 3600 pamphlets. Combining the pamphlets of Leo and Mike 5400 + 400 + 3600 = 9400 pamphlets. The answer is 9400.
Q: Randy has $30. He spent $10 buying his lunch. He spent a quarter of the money he had left on an ice cream cone. What is the amount of money, in dollars, Randy has left?

Question: John has a donkey and an elephant. The elephant weighs 3 tons (a ton is 2000 pounds). The donkey weighs 90% less. What is their combined weight in pounds?
Answer: The elephant weighs 3 * 2000 = 6000 pounds. The donkey weighs 6000 * .9 = 5400 pounds less. So the donkey weighs 6000 - 5400 = 600 pounds. That means the combined weight is 600 + 6000 = 6600 pounds. The answer is 6600.
[Question]For every 1 minute that Carlotta sings on stage during the final opera performance, she spends an additional 3 minutes practicing and 5 minutes throwing temper tantrums. If her final stage performance is 6 minutes long, what is the total combined amount of time, in minutes, that she spends practicing, throwing tantrums, and singing in the final stage performance?
[Answer]For each 6 minutes she performs, Carlotta spends 6 * 3 minutes = 18 minutes practicing. For each 6 minutes she performs, Carlotta throws tantrums for 6 * 5 minutes = 30 minutes. Thus, in total, for each 6 minutes of performance time, she spends 18 minutes + 30 minutes + 6 minutes = 54 minutes on all three activities. The answer is 54.
Q: On a normal day, Julia can run a mile in 10 minutes. However, today she decided to wear her new shoes to run. They were uncomfortable and slowed her mile down to 13 minutes. How much longer would it take Julia to run 5 miles in her new shoes than if she wore her old ones?
A: With her regular shoes, it should take 5 * 10 = 50 minutes to run five miles. If she wore her new shoes it would take 13 * 5 = 65 minutes to run five miles. 65 - 50 = 15 more minutes. The answer is 15.
Question: Michael has $42. Michael gives away half the money to his brother. His brother then buys 3 dollars worth of candy. If his brother has $35 left, how much money, in dollars, did his brother have at first?
