Question: Karen’s work tote bag is twice the weight of her husband Kevin’s briefcase when the briefcase is empty. When Kevin puts his laptop and work papers in his briefcase, it is twice the weight of Karen’s tote. Kevin’s work papers are a sixth of the weight of the contents of his full briefcase. If Karen’s tote weighs 8 pounds, how many more pounds does Kevin’s laptop weigh than Karen’s tote?
Answer: Kevin’s full briefcase is 2 * 8 = 16 pounds. His empty briefcase is 8 / 2 = 4 pounds. The contents of his briefcase weigh 16 - 4 = 12 pounds. His work papers weigh 12 / 6 = 2 pounds. Thus, his laptop weighs 12 - 2 = 10 pounds. Therefore, Kevin’s laptop weighs 10 - 8 = 2 pounds more than Karen’s tote. The answer is 2.
[Question]Sarah walked to school carrying a bag containing 25 apples. At school, she gave each teacher she saw an apple. She also gave a single apple to each of 5 of her closest friends. And while she walked home, she also ate one of the apples. If she had three apples left in the bag when she got home, how many apples had she given away to teachers?
[Answer]Of her original 25 apples, Sarah gave five to friends, meaning she has no more than 25 - 5 = 20 apples available to give to teachers. She ate one while walking home, meaning she had no more than 20 - 1 = 19 apples available to give to teachers. And since she had three apples remaining when she got home, then the amount she had given to teachers was 19 - 3 = 16 apples. The answer is 16.
