conversations.value: I would love to understand how to solve this problem: When Marcus wakes up, his house is 40 degrees. He spends 3 hours baking, and every hour the oven is on it raises the house's temperature by 5 degrees. Then Marcus opens a window for 30 minutes, and the house cools down 2 degrees for every 10 minutes the window is open. What is the house's final temperature?
  Can you explain?

conversations.value: First find the total temperature increase from the oven: 3 hours * 5 degrees/hour = 15 degrees
  Then add that amount to the starting temperature: 15 degrees + 40 degrees = 55 degrees
  Then divide the time the window is open by 10 minutes to find how many 2-degree temperature decreases there are: 30 minutes / 10 minutes = 3
  Then multiply the number of decreases by the amount of each decrease: 3 * 2 degrees = 6 degrees
  Then subtract that amount from the house's temperature after baking to find the final temperature: 55 degrees - 6 degrees = 49 degrees
