If the market value of a car was $6000 exactly 3 years ago, what is its current market value?
(1)starting at the time of purchase, the market value of the car depreciated by 20 percent of its purchase of its purchase price per year.
答案说这个条件不充分是因为这个条件中的car，不一定是题目中的car，可它不是用的the car吗？哇，这种题也太夸张了吧！考试时怎么办？[em26][em26]作者: zyh79 时间: 2002-10-27 20:14
