Answer this question:Maddie watches 8 episodes of a TV show this week. Each episode is about 44 minutes long. If she watches 138 minutes of the show on Monday. She does not watch any TV on Tuesday and Wednesday. On Thursday, she watches 21 minutes. On Friday, she watches 2 episodes. How many more minutes did she watch over the weekend?
