Question: There are 200 snakes in a park. There are three times as many pythons as boa constrictors. If there 40 boa constrictors and the rest of the snakes are rattlesnakes, calculate the total number of rattlesnakes in the park.
Answer: If the number of pythons is three times the number of boa constrictors, then there are 3 * 40 = 120 pythons. Together, the number of pythons and boa constrictors is 120 + 40 = 160. If there are 200 snakes in the park, the number of rattlesnakes is 200 - 160 = 40. The answer is 40.

Question: It cost 50 dollars to get cats ready for adoption, 100 dollars to get adult dogs ready for adoption, and 150 to get puppies ready for adoption. If 2 cats, 3 adult dogs, and 2 puppies are adopted what was the cost to get them ready?
Answer: The cost to get the cats ready is 2 * 50 = $100. The cost to get adult dogs ready is 3 * 100 = $300. The cost to get puppies ready is 2 * 150 = $300. The total cost is 300 + 300 + 100 = $700. The answer is 700.

Question: 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?
Answer:
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.
