Question: At Mrs. Dawson's rose garden, there are 10 rows of roses. In each row, there are 20 roses where 1/2 of these roses are red, 3/5 of the remaining are white and the rest are pink. How many roses at Mrs. Dawson's rose garden are pink?
Answer: There are 20 x 1 / 2 = 10 red roses in each row. So there are 20 - 10 = 10 roses that are not red in each row. Out of the 10 remaining roses in each row, 10 x 3 / 5 = 6 roses are white. Thus, there are 10 - 6 = 4 pink roses in each row. Therefore, Mrs. Dawson has 4 pink roses each in 10 rows for a total of 4 x 10 = 40 pink roses in her rose garden. The answer is 40.
[Question]There are 160 tissues inside a tissue box. If Tucker bought 3 boxes, and used 210 tissues while he was sick with the flu, how many tissues would he have left?
[Answer]When Tucker buys the tissue boxes, he has a total of 160 x 3 = 480 tissues. When he is sick with the flu and uses some of the tissues, he has 480 - 210 = 270 tissues left. The answer is 270.
Q: 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?
A: 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: Nina wants to buy a new video game with her allowance money. The game cost 50 dollars. Nina also has learned that there is a 10 percent sales tax. She receives 10 dollars a week as an allowance, and thinks she can save half of that. How many weeks will it take for Nina to be able to buy the new video game with her savings?
Answer: The 10 percent tax on 50 dollars will be 10 / 100 x 50 = 5 dollars. The cost of the game and the tax will be 50 + 5 = 55 dollars. Nina will save half of her allowance every week, or 10 / 2 = 5 dollars per week. The total cost of the game and tax, divided by Nina's weekly savings is 55 / 5 = 11 weeks. The answer is 11.
[Question]Jim ran 16 miles in 2 hours while Frank ran 20 miles in 2 hours. How many more miles did Frank run than Jim in an hour?

[Question]John manages to run 15 mph for his whole 5-mile race. The next fastest guy ran the race in 23 minutes. How many minutes did he win the race by?
[Answer]
He runs the race in 5 / 15 = 1 / 3 of an hour. So he runs the race in 60 / 3 = 20 minutes. That means he beat the next fastest guy by 23 - 20 = 3 minutes. The answer is 3.
