(400-130)X10+(2500-600)X2=2700+3800=6500
6500÷2500=260%
答：利润为6500,利润率为260%.

买进来的成本总价=130X10+600X2=2500
卖出去的价格=400X10+2500X2=9000
利润率=（9000-2500/2500=260%

求虐。。。。。。。。。。高一了、、、、、、、、不会、、、、、、、

题目的意思大致是早些年，悠悠以每千克130的价格买了10千克的茶a，以600每千克的价格买了2千克的茶b，那么她现在分别以400和2500每千克的单价将两种茶全卖了。请问，总的来说，利润率是多少。
我只负责翻译，不过还是说说我的结果是2.6%

买进茶叶总共花了130×10+600×2=2500元
卖出全部茶叶获得400×10+2500×2=9000元
