Q: There are one hundred tickets to be sold for a volleyball game. Andrea sold twice as many tickets as Jude while Sandra sold 4 more than half the number of tickets Jude sold. If Jude sold 16 tickets, how many tickets need to be sold?
A: Andrea sold 16 x 2 = 32 tickets. Half the number of tickets Jude sold is 16 / 2 = 8. So, Sandra sold 8 + 4 = 12 tickets. Thus, Andrea, Jude, and Sandra sold a total of 32 + 16 + 12 = 60 tickets. Therefore, 100 - 60 = 40 tickets need to be sold. The answer is 40.

Q: 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?
A: Maddie watches a total of 8 * 44 = 352 minutes of the TV show during the week. On Friday, she watches 2 * 44 = 88 minutes. On Monday, Thursday, and Friday, she watches 138 + 21 + 88 = 247 minutes. Thus, on the weekend she watches 352 - 247 = 105 minutes of the TV show. The answer is 105.

Q: If Amanda can run the length of a football field 2000 meters in length in 2 hours, how long would it take her to run the length of a 10000-meter track at the same speed?
