Q. The table below 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?
Month Average Price per Dozen
The table below shows the average (arithmetic mean) price per dozen of the large grade A eggs
1.26 = x/12 ---> x = 15.12
1.20 = x/12 ---> x = 14.40
1.08 = x/24 ---> x = 25.92
15.12 + 14.40 + 25.92 = 55.44
55.44/(12 + 12 + 24) = 55.44/48 = 1.155 = 1.16
I get D.
Is anyone up for solving the first one? I'd like to see a quick way to do that one.
