[Question]At the polar bear club, Jerry and his three friends, Elaine, George, and Kramer, took turns jumping into a swimming pool filled with freezing-cold water. Jerry was in the pool for 3 minutes before becoming too cold to remain in the cold water. Elaine stayed in the pool for twice as long as Jerry. George could only stay in the pool for one-third as long as Elaine. And Kramer, who accidentally locked himself in the bathroom, could not find the pool. What is the combined total of minutes that Jerry and his friends were in the cold water?
[Answer]Elaine was in the pool for 2 * 3 = 6 minutes. George was in the pool for 6 / 3 = 2 minutes. Kramer never found the pool and thus swam for 0 minutes. In total, Jerry and his friend were in the cold water for 3 + 6 + 2 + 0 = 11 minutes. The answer is 11.
Q: Robert had 25 balls. Tim gave him half of his 40 balls. How many balls does Robert have now?

Question: It takes 3 men an hour to complete a job. If they are hired to work on 5 such similar jobs by a company that pays each of them $10 per hour, calculate the total amount of money the three will earn when they complete the jobs?
Answer: Since they are paid $10 each per hour of work and can complete a job in one hour, they earn a total of $10 * 3 = $30 together for an hour of work. If they earn together $30 for one job, for the five jobs, they'll earn $30 * 5 = $150. The answer is 150.
[Question]John cuts his grass to 2 inches. It grows .5 inches per month. When it gets to 4 inches he cuts it back down to 2 inches. It cost $100 to get his grass cut. How much does he pay per year?
[Answer]He cuts his grass 4 - 2 = 2 inches. So he gets it cut every 2 / .5 = 4 months. That means he gets it cut 12 / 4 = 3 times a year. So he pays 100 * 3 = $300 per year. The answer is 300.
Q: Nancy and Jason are learning to dance for the first time. Nancy steps on her partner's feet 3 times as often as Jason. If together they step on each other's feet 32 times, how many times does Jason step on his partner's feet?
A: Let n be the number of times Nancy steps on her partner's feet and j be the number of times Jason does. We know that n = 3j and n + j = 32. Substituting the first equation into the second equation, we get 3j + j = 32. Combining like terms, we get 4j = 32. Dividing both sides by 4, we get j = 8. The answer is 8.
Question: If Beth is 18 years old and her little sister is 5, in how many years would she be twice her sister's age?
Answer:
The age difference between Beth and her sister is 18 - 5 = 13 years. Beth must be 13 x 2 = 26 to be twice her sister's age. Beth will be twice her sister's age in 26 - 18 = 8 years. The answer is 8.
