※ 引述《si4410dy (si4410dy)》之铭言： : 17. (26864-!-item-!-188;#058&003368) : At present the Hollywood Restaurant has only standard-height tables. : However, many customers come to watch the celebrities who frequent the : Hollywood, and they would prefer tall tables with stools because such seating : would afford a better view of the celebrities. Moreover, diners seated on : stools typically do not stay as long as diners seated at standard-height : tables. Therefore, if the Hollywood replaced some of its seating with high : tables and stools, its profits would increase. ^^^^^^^ : The argument is vulnerable to criticism on the grounds that it gives reason : to believe that it is likely that : (A) some celebrities come to the Hollywood to be seen, and so might choose to : sit at the tall tables if they were available : (B) the price of meals ordered by celebrities dining at the Hollywood : compensates for the longer time, if any, they spend lingering over their meals : (C) a customer of the Hollywood who would choose to sit at a tall table would : be an exception to the generalization about lingering : (D) a restaurant's customers who spend less time at their meals typically : order less expensive meals than those who remain at their meals longer ^^^^^^^^^^^^^^ : (E) with enough tall tables to accommodate all the Hollywood's customers : interested in such seating, there would be no view except of other tall tabl : OA:C : 想请问这题的D选项 : 花较少时间吃饭通常点的较便宜，反之亦然 : 为何不能这样解: : 部分换成高脚桌椅的点的变成较便宜所以profit不会increase 便宜指的是价格高低 profit指的是中间的利润 这之间没有直接的关联，因为缺乏「成本」这个因素 单位利润＝单位价格-单位成本 所以便宜的餐点搞不好成本很低很低，profit反而高 比较贵的餐点搞不好成本非常高，反而赚不到多少钱 这也是自修影片中有讲到的「动态平衡」概念（10'25"开始） http://youtu.be/R3zI42gZdSQ?t=10m25s Dustin -- Dustin Deng (一战自修760，AWA 5.5) [email protected] Dustin SC专班： http://a2gmat.blogspot.tw/p/sc.html Dustin的GMAT自修频道： https://www.youtube.com/user/danyuchn/videos 台湾GMAT心得文资料库： http://taiwangmatexp.blogspot.tw --
