Question: Mrs. Carlton gives out penalty points whenever her students misbehave. They get 5 points for interrupting, 10 points for insulting their classmates, and 25 points for throwing things. If they get 100 points, they have to go to the office. Jerry already interrupted twice and insulted his classmates 4 times. How many times can he throw things before he gets sent to the office?
Answer: For interrupting, Jerry got 5 points per interruption * 2 interruptions = 10 points. For insulting, he got 10 points per insult * 4 insults = 40 points. To get to the 100 limit points, Jerry has 100 points - 10 points - 40 points = 50 points left. He still has 50 points / 25 points per throw = 2 throws. The answer is 2.
[Question]Jenny's property tax rate is 2%. Her house is currently worth $400,000. The city is about to build a new high-speed rail project nearby, which will increase her house's value by 25%. Jenny can only afford to spend $15,000/year on property tax. How many dollars worth of improvements can she make to her house before her property tax bill gets too high?
[Answer]First find how much the rail project will increase the house value by multiplying the initial value by 25%: $400,000 * .25 = $100,000. Then add that amount to the initial value to find the new value: $100,000 + $400,000 = $500,000. Then divide the maximum amount of property tax Jenny can afford to pay by the property tax rate to find the maximum value her house can have: $15,000 / .02 = $750,000. Now subtract the house's value after the rail project from the maximum value to find how much value the improvements can have: $750,000 - $500,000 = $250,000. The answer is 250000.

A: The students' entrance fee cost $5 x 35 = $175. The adults' entrance fee cost $6 x 4 = $24. Therefore, the school will pay a total of $175 + $24 = $199 for the farm entrance. The answer is 199.
Question: Daisy is a poodle puppy who loves to play with her dog toys. She often loses them in various ways, and her owner needs to replace them. On Monday, Daisy played with 5 dog toys. On Tuesday, Daisy had 3 dog toys left after losing some, and her owner went to the store and got her 3 more. On Wednesday, all of Daisy's old and new dog toys were missing, so her owner went to the store and bought her 5 more. If Daisy's owner found all the lost dog toys, including the new dog toys, how many dog toys would Daisy have now?
Answer: Daisy originally had 5 dog toys on Monday + 3 more her owner bought her on Tuesday = 8 dog toys. On Wednesday Daisy's owner bought her 5 more dog toys + 8 old ones = 13 total dog toys if none were lost. The answer is 13.
Q: Tom's rabbit can run at 25 miles per hour. His cat can run 20 miles per hour. The cat gets a 15-minute head start. In hours, how long will it take for the rabbit to catch up?
A:
The cat got a 15 / 60 = .25 hour head start. That means it ran 20 * .25 = 5 miles. The rabbit goes 25 - 20 = 5 mph faster than the cat. So it takes 5 / 5 = 1 hour for the rabbit to catch up. The answer is 1.
