Q: A cookfire burns three logs every hour. It was built with six logs to start. If it gets two more logs added to it at the end of every hour, how many logs will be left after 3 hours?
A: After 3 hours, it will have 3 * 2 = 6 logs added to it. After 3 hours, it will have burned 3 * 3 = 9 logs. After 3 hours, the cookfire will have 6 + 6 - 9 = 3 logs left. The answer is 3.

Q: The temperature in New York in June 2020 was 80 degrees. If the temperature in Miami on this day was 10 degrees hotter than the temperature in New York, and 25 degrees cooler than the temperature in San Diego, what was the average temperature for the three cities?
A: If it was 10 degrees hotter on this day in Miami than in New York, then the temperature in Miami was 80 + 10 = 90 degrees. If it was 25 degrees cooler in Miami than in San Diego, then the temperature in San Diego was 90 + 25 = 115 degrees. The total temperature for all the cities is 115 + 90 + 80 = 285 degrees. The average temperature of the three cities is 285 / 3 = 95 degrees. The answer is 95.

Q: Jill and Bob want to finally buy a house for themselves, so they went with a real estate agent to see some houses before making a decision. The first house was not too far from their work and the price was accessible. The second house was really big and Jill loved it but was twice as expensive as the first one and was way over their budget. They ended up buying the first one, knowing that the price of both houses altogether is $600,000. How much did Jill and Bob end up paying for their new house?
A:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

Let C be the cost of the first house. The cost of the second house is 2C. The cost of the two houses together is C + 2C = $600,000. 3C = $600,000. C = $600,000 / 3 = $200,000. The answer is 200000.
