Question: Ben has four boxes with ten basketball cards in each box. His mother gave him five boxes with eight baseball cards. If he gives 58 cards to his classmates, how many cards does he has left?
Answer: Ben has 4 x 10 = 40 basketball cards. His mother gave him 5 x 8 = 40 baseball cards. Thus, Ben has 40 + 40 = 80 cards in all. Therefore, Ben has 80 - 58 = 22 cards left. The answer is 22.
[Question]Michelangelo has 28 ceilings to paint. This week, he paints 12 of them. Next week, he will paint 1/4 the number of ceilings he did this week. How many ceilings will be left to paint after next week?
[Answer]After this week, Michelangelo will have 28 - 12 = 16 more ceilings to paint. Next week, Michelangelo will paint 12 / 4 = 3 ceilings. Michelangelo will have 16 - 3 = 13 more ceilings to paint. The answer is 13.
Q: A car is driving through a tunnel with many turns. After a while, the car must travel through a ring that requires a total of 4 right-hand turns. After the 1st turn, it travels 5 meters. After the 2nd turn, it travels 8 meters. After the 3rd turn, it travels a little further and at the 4th turn, it immediately exits the tunnel. If the car has driven a total of 23 meters around the ring, how far did it have to travel after the 3rd turn?
A: From the details given, the car has traveled 5 meters at the 1st turn + 8 meters after the 2nd turn + 0 meters after the 4th turn = 13 meters around the ring. It must therefore have driven 23 total meters – 13 calculated meters = 10 meters after the 3rd turn. The answer is 10.
Question: Susan wants to throw a party for her mom. She is planning on having 30 guests. For dinner she is making a recipe that makes 2 servings each. Each batch of the recipe calls for 4 potatoes and 1 teaspoon of salt. A potato costs $.10 and a container of salt costs $2 at the supermarket. If each container of salt has 5 teaspoons, how much money will Susan spend on food?
Answer: Susan needs to make 30 / 2 = 15 batches of the recipe. Therefore, she will need 15 * 4 = 60 potatoes. She will also need 1 * 15 = 15 teaspoons of salt. Thus she will have to buy 15 / 5 = 3 containers of salt. Therefore, she will spend 60 * $.1 = $6 on potatoes and 3 * $2 = $6 on salt. Thus, she will spend $6 + $6 = $12 on food. The answer is 12.

50 x 60 / 100 = 30 people support the first team. 50 x 34 / 100 = 17 people support the second team. So, a total of 30 + 17 = 47 people supported the first and second teams. Thus, 50 - 47 = 3 people did not support either team. The answer is 3.
