Question: Mr. McNeely takes a register of the total number of students present in class every day. On a particular week, the number of students in the class on the second day was 40 more than the first day. The number of students who didn't turn up for the class on the second day was twice the number of students who didn't turn up on the third day. On the third day, 1/7 of the total number of students of the class called in sick. If the total number of students in the class is 280, calculate the number of absent students in the three days.
Answer: On the third day, 1 / 7 * 280 = 40 students called in sick. If the number of students absent on the second day was twice the number on the third day, then 2 * 40 = 80 students didn't show up for the class on the second day. The total number of students present in the class on the second day was 280 - 80 = 200. If 40 fewer students showed up for the class on the first day than on the second day, then 200 - 40 = 160 students showed up for the class on the first day. The number of students absent on the first day is 280 - 160 = 120. In the three days, the total number of absentees is 120 + 80 + 40 = 240. The answer is 240.
[Question]Willow’s daughter had a slumber party with 3 of her friends. For breakfast, they wanted pancakes. Willow’s pancake recipe makes 1 serving of 4 pancakes. Each of the girls wanted a serving and a half of pancakes. Willow’s son wanted 3 servings of pancakes. How many single pancakes will Willow make for the girls and her son?
[Answer]The daughter and her 3 friends each want 1.5 servings of pancakes so that’s 4 * 1.5 = 6 servings of pancakes. Willow’s son wants 3 servings of pancakes and the girls want 6 so that’s 3 + 6 = 9 servings of pancakes. Each serving makes 4 pancakes and Willow needs to make 9 servings for a total of 4 * 9 = 36 pancakes. The answer is 36.
[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.
