454. a store sells computer A and computer B. Computer A is sold tiwce the price of computer B,the gross profit of computer A is 80% of the price at which the store purchased computer A , and the gross profit of computer B is 20% of the price at which the store purchased computer B
60%那个
还有这道题,我想问个问题gross profit应该就是毛利率,对吧?是没有deduction的阿,也就是包含成本的阿,the price at which the store purchased the computer也就是成本阿!我觉得有可能是我理解的问题,下月考试,希望能把这些搞清楚一些,谢谢大家
