Q. Based on Exhibit 1, which of the following provides the strongest evidence that Chrome displays economies of scale?
选项：
A.Increasing net sales
B.Profit margins that are increasing with net sales
C.Gross profit margins that are increasing with net sales
解释：
C is correct. Economies of scale are a situation in which average costs decrease with increasing sales volume. Chrome’s gross margins have been increasing with net sales. Gross margins that increase with sales levels provide evidence of economies of scale, assuming that higher levels of sales reflect increased unit sales. Gross margin more directly reflects the cost of sales than does profit margin.
一般都是用gross profit判断吗
