First-time computer buyers buying PXC home computers typically buy models that cost much less and have a smaller profit margin per computer than do PXC computers bought by people replacing their computers with more powerful models. Last year PXC's profits from computer sales were substantially higher than the previous year, although about the same number of PXC computers were sold and the prices and profit margins for each computer model that PXC sells remained unchanged.
If the statements above are true, which of the following is most strongly supported by them?
(A) PXC's competitors raised the prices on their computers last year, making PXC computers more attractive to first-time computer buyers.
(B) The number of people buying PXC computers who also bought PXC computer-related products, such as printers, was larger last year than the previous year.
(C) Among computer buyers who bought a PXC computer to replace their existing computer, the proportion who were replacing a computer made by a competitor of PXC was greater last year than the previous year.
(D) The proportion of PXC computers bought by first-time computer buyers was smaller last year than the previous year.
(E) PXC's production costs for its computers were lower last year than they had been the previous year.
哪位大侠指导一下这个~~答案是D,不明白呀...THX!!!!!!!!!
more powerful models 利润好
much less and have a smaller profit margin models 利润低
所以消费者数量不变的话
买powerful 得越多，买less powerful 得越少，
总利润也就越好。
但是E选项不是说成本下降就可以解释利润上升了 OPEN TO DISCUSS
回resource0407
请注意profit margin没变
虽然production cost少了，但可能物流费用上去了，举个例子
profit margin才是最关键的
解释的好清楚呀
