Q: Tim watches 2 shows. One of them is a half-hour show per episode and the other is a 1-hour long show per episode. The short show had 24 episodes and the long show had 12 episodes. How many hours of TV did he watch?

Question: A class is completing an art project. Each of the 30 students is assigned to a separate group and will need to take markers from the 22 boxes of markers. The first group has 10 students who will have 2 markers each and the second group has 15 students who will have 4 markers each. The last group takes the remaining markers and divides them equally. If each box of markers contains 5 markers, how many markers does each of the students in the last group receive?
Answer: The first group uses a total of 10 students * 2 markers = 20 markers. The second group uses a total of 15 students * 4 markers = 60 markers. This is a total of 20 + 60 = 80 markers. The total number of markers in the boxes is 5 markers * 22 boxes = 110 markers. This leaves 110 – 80 = 30 markers for the last group to split between themselves. The last group is made up of 30 total students – 10 students in the first group – 15 students in the second group = 5 students. Therefore, students in the last group receive 30 markers / 5 students = 6 markers each. The answer is 6.
[Question]John can play 200 beats per minute. If he plays 2 hours a day for 3 days how many beats does he play?
[Answer]He trains 2 * 60 = 120 minutes a day. That means he played 200 * 120 = 24000 beats per day. So he played 24000 * 3 = 72000 beats. The answer is 72000.
Q: While at Wizards Park, Kate buys 3 magic wands, one for herself and two for her friends. When she returns she sells the wands to her friends for $5 more than she paid. If she collected $130 after the sale, how much money did each wand cost?
A: Out of 3 wands purchased, Kate sold her friends 3 wands - 1 wand = 2 wands. For 2 wands she charged $130, so for 1 wand she charged $130 / 2 wands = $65 / wand. Since she charged $5 more for each wand than she paid, Kate paid $65 - $5 = $60 for each wand. The answer is 60.
Question: Lyle wants to buy himself and his friends a sandwich and a pack of juice. A sandwich costs $0.30 while a pack of juice costs $0.2. If Lyle has $2.50, how many of his friends can have a sandwich and a pack of juice?
Answer: A sandwich and a pack of juice cost $0.3 + $0.2 = $0.50. With Lyle's $2.50, he can buy $2.50 / $0.50 = 5 sets of sandwiches and juice. Therefore, 5 - 1 = 4 of his friends can have a sandwich and a pack of juice since the other 1 set is for Lyle himself. The answer is 4.
