The table above shows the average (arithmetic mean) price per dozen eggs sold in a certain store during three successive months. If 2/3 as many dozen were sold in April as in May, and twice as many were sole! in June as in April, what was the average price per dozen of the eggs sold over the three-month period?
选项
A、$1. 08
B、$1. 10
C、$1. 14
D、$1. 16
E、$1. 18
答案
D
解析
Given that the numbers of eggs sold in each of the three months are in the ratio 2:3:4, it follows that 2/9 of the eggs sold in the three-month period were sold at an average of $1.26 per dozen, 3/9 = 1/3 were sold at $1.20 per dozen, and 4/9 were sold at $1.08 per dozen. Therefore, the average price per dozen of the eggs sold in the three-month period was 2/9($1.26)+ 1/3($1.20)+ 4/9($1.08) =$1.16. The correct answer is D.
