: 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
: 想請問這題的D選項
: 花較少時間吃飯通常點的較便宜，反之亦然
: 為何不能這樣解:
: 部分換成高腳桌椅的點的變成較便宜所以profit不會increase
便宜指的是價格高低 profit指的是中間的利潤
這之間沒有直接的關聯，因為缺乏「成本」這個因素
單位利潤＝單位價格-單位成本
所以便宜的餐點搞不好成本很低很低，profit反而高
比較貴的餐點搞不好成本非常高，反而賺不到多少錢
這也是自修影片中有講到的「動態平衡」概念（10'25"開始）
