How many dozen AA large eggs will you need to make an angel cakeformula 10 times if the formula calls for 3 lb 7 oz of egg whites? Giveyour answer in whole dozens. A dozen large eggs weigh 24 oz, and theegg white yield on an egg is 53%.

Sagot :

AA large eggs have an average weight of 2 oz.

Then, in a whole dozens you have 24 oz.

In order to determine how many eggs do you need, you consider that the angel cake formula requires 3 lb 7 oz of egg whites, furthermore, you consider that 1 lb = 16 oz. Then, the total weight in oz units of the required eggs is:

3 lb + 7 oz = 3 (16 oz) + 7 oz = 48 oz + 7 oz = 55 oz

Now, you take into account that only 53% of an egg is egg white. You calculate the equivalent weight of this percentage, as follow:

0.53(2 oz) = 1.06 oz

then 1.06 oz is egg white.

Finally, tou calculate the quotient between the weight of the required egg whites (55 oz) between the weight of egg white for one egg (1.06z):

55/1.06 = 51.88 (you approximate to the higher whole number)

55/1.06 52

Hence, you need 52 eggs to make the angel cake. This result in dozens is:

52/12 = 4.33 4.5 = 4 1/2

Hence, you required of aproximately 4 and one half dozens
