近年来在中考试题中,商品销售问题已成为应用题的热点素材,其中不少题目可列分式方程求解,下面举例分析,供同学们学习参考.一、销售利润问题例1商场销售某种商品,今年四月份销售了若干件,共获毛利润3万元(每件商品的毛利润=每件商品的销售价格-每件商品的成本价格).五月份,商场在成本价格不变的情况下,把这种商品的每件销售价格降低了4元,但销售量比四月份增加了500件,从而所获毛利润比四月份增加了2000元.问调价前销售每件商品的毛利润是多少元?
In recent years, in the mid-test questions, the problem of commodity sales has become a hot topic for application problems, many of which can be solved by fractional equations. The following examples are analyzed for the students to learn and reference.
