Question: Frank spent 1/5 of his money to buy groceries. He then spent 1/4 of the remaining money to buy a magazine. If he had $360 left in his wallet, how much money did he have at first?
Answer: Let X be the money Frank had originally. Frank spent 1 / 5 * X on groceries. Frank spent 1 / 4 * (X - 1 / 5 * X) on a magazine. Frank has X - 1 / 5 * X - 1 / 4 * (X - 1 / 5 * X) = $360 left in his wallet. Multiplying through the parentheses, we get X - 1 / 5 * X - 1 / 4 * X + 1 / 20 * X = $360. Combining like terms, we get 12 / 20 * X = $360. Dividing both sides by 12 / 20, we get X = $600. The answer is 600.

Question: There were 8000 jelly beans in a certain barrel, and 10 people lined up to take some. The first six people each took twice as many jelly beans as each of the last four people took. If the last four people each took 400 jelly beans, how many jelly beans remained in the container?
Answer: If the last four people each took 400 jelly beans, they took a total of 4 * 400 = 1600 jelly beans. The first six people each took twice as many jelly beans as each of the last four people took, meaning each of them took 2 * 400 = 800 jelly beans. The total number of jelly beans the first six people took is 800 * 6 = 4800 jelly beans. Together, all 10 people took together 4800 + 1600 = 6400 jelly beans. If there were 8000 jelly beans in a certain barrel, the number of jelly beans that remained is 8000 - 6400 = 1600. The answer is 1600.
[Question]Tom's brother is 4 times as old as Tom's dog. If in 6 years, Tom's brother will be 30 years, how old is Tom's dog going to be in six years?
[Answer]If in six years Tom's brother will be 30 years old, he is currently 30 - 6 = 24 years old. Since Tom's brother is 4 times as old as Tom's dog, Tom's dog is 24 / 4 = 6 years old currently. Tom's dog will be 6 + 6 = 12 years old in six years. The answer is 12.
