Indicate all such statements.

A For 2008 the dollar amount of sales at Store R was greater than that at each of the other four stores.

B The dollar amount of sales at Store S for 2008 was 22 percent less than that for 2006.

C The dollar amount of sales at Store R for 2008 was more than 17 percent greater than that for 2006.

本题A选项一看到就可以排除了，涉及到两个店的绝对量的比较，这个不确定，没有告诉绝对值。B选项是把两个增长的比例简单地算术相加。肯定错了。所以C肯定是对的了。。算一下也是的确是对的。。
