题目
A collection of books went on sale, and 2/3 of them were sold for $2.50 each. If none of the 36 remaining books were sold, what was the total amount received for the books that were sold?
选项
A. $180
B. $135
C. $90
D. $60
E. $54
答案:A
解题思路:
Since 2/3 of the books in the collection were sold, 1/3 were not sold. The 36 unsold books represent 1/3 of the total number of books in the collection, and 2/3 of the total number of books equals 2(36) or 72. The total proceeds of the sale was 72($2.50) or $180. The best answer is therefore A.
