卖出的价格是：卖价=买价+卖价的40% 卖出的价格=150+40%卖出的价格
所以卖出的价格是：250刀
毛利就是：250-150=100刀
如果是set the selling price equal to the purchase price plus a markup that was 40 percent of the purchase price，则 卖价=买价+40%买价, b=150+150*0.4-->b=210
加价是售价的40%。设售价sp=X 根据条件可以得到一个关于X的等式 X=150+40%X，得sp=250 gross profit=SP-GOGS（成本）=250-150=100登录 或 注册 后可以参加讨论
