Month Average price per dozen
April $1.26 May$1.20
June $1.08 The table above shows the average (arithmetic mean) price per dozen of the large grade A eggs sold in a certain store during three successive months. If as many dozen were sold in April as in May, and twice as many were sold in June as in April, what was the average price per dozen of the eggs sold over the three-month period?

Set:
x = Number of dozen sold in April
x = Number of dozen sold in May
2x = Number of dozen sold in June

Want to find: Total Money / Total Number
Total Money = 1.26x + 1.2x + 1.08*2*x = 4.62x
Total Number = x+x+2x = 4x

Ans = 4.62x / 4x = 1.155

I come up with 1.14 as the average price..

April $1.26 x May$1.2 x

June 1.08 2x

sum = 4.56x/ 4x = 1.14
