左边是说:so that at least one person receives at least $3 这句话的意思不是至少一个人得到至少3块吗?这样的话,不用每个人都要得到3块也可以。是不是这样呢?

还有san道题 请楼主帮忙,多谢多谢~~~~~
猴哥106题 因为是图题,我把题目放在这儿吧 What is the greatest number of the companies surveyed that could have offered both the compressed-workweek option and the work-at-home option?
答案 27
87.题中的 T is no smaller than a number 20 percent less than the integer x. if T=60
这句话用句子怎么表述呢?
90. Rack A holds 80 pairs of slacks with prices ranging from $12 to $15 a pair, and rack B holds 60 pairs of slacks with prices ranging from $13 to $18 a pair. If all the slacks are sold, what is the greastest amount by which the revenue from the sale of slacks on rack A could possibly exceed the revenue from the sale of slacks on rack B?
答案是 ¥412
解答:
1.不好意思,我没图
2. 如果把句子改成T is no smaller than a number which is 20 percent less than the integer x,是不是能理解了呢?
3.问A比B最多赚多少?那么A最多赚79*15+12,B最少赚13*59+18(因为有个范围,表示必须有上下限的,不能都是上限或者都是下限),两者相减得412
