※ 引述《Levitan (荣哥 )》之铭言： : 不好意思麻麻烦板上的强者,下面这两题我想了好久 : 看了解答还有不太了解,希望解答一下.谢谢! <(_ _)> : 第36题 : The profit from the sale of a certain appliance increases, : though not proportionally, with the number of units sold. : Did the profit exceed four dollars million on sales of 380,000 : units? : (1) The profit exceeded two million dollars on sales of 200,000 : units. : (2) The profit exceeded five million on sales of 350,000 units. 题目说，利润随着销售数量增加而提升，但不会呈现线性关系 问你若出售380,000个商品，利润会否超过$4 million? (1)出售200,000个商品利润超过$2 million 因为不是线性关系，所以不知道是否符合题目 (2)既然仅出售350,000个商品利润就超过$5 million 那麽多出售30,000个不会赚更少吧?(前提:利润随销售数量增加而提升) : 第55题 : At a certain picnic, each of the guests was served either a single : scoop or a double scoop of ice cream. How many of the guests were : served a double scoop of ice cream? : (1) At the picnic, 60 percent of the guests were served a double : scoop of ice cream. : (2) A total of 120 scoops of ice cream were served to all the guests : at the picnic. 在一次活动中，每个人可得到一球or两球冰淇淋，有多少人得两球? (1)有60%的人得到两球-->不知道总人数无法得知......insufficient (2)总共发了120球-->不知道比例无法得知......insufficient (1)+(2)比例&总数都知道当然可以求出......sufficient --
