问题 解答题

和谐商场销售甲、乙两种商品,甲种商品每件进价15元,售价20元;乙种商品每件进价35元,售价45元。

(1)若该商场同时购进甲、乙两种商品共100件,恰好用去2700元,求能购进甲、乙两种商品各多少件?

(2)该商场为使甲、乙两种商品共100件的总利润(利润=售价-进价)不少于750元,且不超过760元,请你帮助该商场设计相应的进货方案。

答案

解:(1)设该商场购进甲种商品x件,根据题意可得:15x+35(100-x)=2700,

解得:x=40;乙种商品:100-40=60(件),

答:该商场购进甲种商品40件,乙种商品60件。

(2)设该商场购进甲种商品a件,则购进乙种商品(100-a)件,根据题意得:

解得:48≤a≤50;

∴a是正整数,

∴a=48或a=49或a=50;

∴进货方案有三种:

方案一:购进甲种商品48件,购进乙种商品52件

方案二:购进甲种商品49件,购进乙种商品51件

方案三:购进甲种商品50件,购进乙种商品50件。
