When eggs are differentiated by their grade and weight, comparative prices are one factor. All
factors, other than weight, being equal, which is the better buy is the question to be resolved.

Example: What is the price per pound for large eggs (24 oz/doz) selling at $2.52/doz?

Solution:
Price per doz x 16 oz / lb. =
oz/doz

$2.52 / doz x 16 oz / lb. =
24 oz/doz

$0.105 x 16 oz / lb. =

$1.68 oz / lb.

Nutritionally there is no difference between a Grade AA egg, a Grade A egg or a Grade B egg
when the eggs are the same weight. There will be a difference when the weights differ, but that is a
percentage factor of each nutritional element for the weight. Review the grading standards for eggs 12
and you will note that the grades do not list or identify the nutritional values. However, the
wholesomeness element will affect the grade because there are different elements that show up during
candling which will cause the egg to be rejected. Examples include: blood spots; worms; mold; and,
other objects that show up during candling.
Sometimes shoppers will compare pricing for value. The same calculation is made as in the
previous example and each is compared to price and egg size weight.

Example: Compare one dozen Extra Large eggs for $2.58 or one dozen Large eggs for $2.54.
Comparing on a per pound basis, if Extra Large eggs average 27oz/doz, and the Large
eggs average 24oz/doz, (a) which is the better buy and (b) the price difference/lb?
(a) _________________ Better buy.
(b) __________ Price Difference/lb.
Solution:

(a) Price per doz x 16 oz / lb. = Price / pound
oz/doz

In comparing the two prices by weight, their cost per unit weight must be computed. Since the
extra large eggs average 27oz/doz, then the cost per Pound is:

Extra Large eggs
$2.58 / doz x 16 oz / lb. = Price / pound
27oz / doz

$0.096 x 16 oz / lb. = $1.53 / pound for Extra Large eggs.

Large eggs average 24 oz/doz and their cost is $2.54 doz x 16oz/lb,

or $2.54 / doz x 16
24 oz / doz = $1.69 / pound for Large eggs

(a) Extra Large eggs are the better buy (they cost less) from the standpoint of weight per dozen.

(b) Price Difference:

More Expensive − Less Expensive = Price Difference
(b) 1.69 / lb − 1.53 / lb = $0.16 / lb
