新世纪广场进货员预测一种应季衬衫能畅销市场，就用8万元购进这种衬衫，面市后果然供不应求，商场又用17.6万元购进了第二批这种衬衫，所购数量是第一批购进量的2倍，但单价贵了4元，商场销售这种衬衫时每件定价都是58元，最后剩下的150件按八折销售，很快售完，在这两笔生意中，商场共赢利多少元？
设商场第一次购进x件衬衫，则第二次购进2x件，
根据题意得：
=80000 x
-4．176000 2x
160000=176000-8x
解这个方程得：x=2000．
经检验：x=2000是原方程的根．
∴2x=4000
商场利润：（2000+4000-150）×58+58×0.8×150-80000-176000=90260（元）．
答：在这两笔生意中，商场共盈利90260元．
