[Question]Chantal knits sweaters to sell. Each sweater takes 4 balls of yarn. Each ball of yarn costs $6. How much money will Chantal gain in all 28 sweaters if she sells each sweater for $35?
[Answer]The 28 sweaters need 28 x 4 = 112 balls of yarn. So, Chantal will spend 112 x $6 = $672 in all for the balls of yarn. Her total earnings for selling 28 sweaters is $35 x 28 = $980. Therefore, Chantal will gain $980 - $672 = $308. The answer is 308.
Q: For every 12 cans you recycle, you receive $0.50, and for every 5 kilograms of newspapers, you receive $1.50. If your family collected 144 cans and 20 kilograms of newspapers, how much money would you receive?
A: There are 144 / 12 = 12 sets of 12 cans that the family collected. So, the family would receive $0.50 x 12 = $6 for the cans. There are 20 / 5 = 4 sets of 5 kilograms of newspapers that the family collected. So, the family would receive $1.50 x 4 = $6 for the newspapers. Therefore, the family would receive a total of $6 + $6 = $12. The answer is 12.

[Question]Samira is the assistant coach of a soccer team playing against one of the best teams in their league. She has four dozen water bottles filled with water in a box. In the first break of the match, the 11 players on the field each take two bottles of water from Samira's box, and at the end of the game, take one more bottle each. How many bottles of water are remaining in Samira's box?
[Answer]If the box has four dozen bottles of water, there are 4 * 12 = 48 bottles of water in the box. After the first half, the 11 players take 11 * 2 = 22 bottles of water from the box. If they take 11 more bottles of water at the end of the game, the number increases to 22 + 11 = 33 bottles of water taken. Without the bottles taken, there are 48 - 33 = 15 bottles of water remaining in the box. The answer is 15.
