99原三 http://ppt.cc/94nm 考題和解法主要問題是第一小題 (一)記憶卡價格下降 ------------------------------------ 題目: 數位相機與數位相機... 記憶卡則是這兩種商品之互補品 ------------------------------------ 解法: 記憶卡下降藍色 S增加=>P上升,數量增加黑色 S增加=>P上升,數量增加 D增加=>P下降,數量增加最後價格不一定,但數量增加 ------------------------------------ 兩本書寫法不太一樣不知道那個才是對的? (我個人覺得是黑的) -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 111.240.33.30
