Now, you need to break up these prices per dish. You'll need to know how much of each ingredient you use per dish.
For your omelet dish example, each omelet dish with potatoes and bacon uses 3 eggs, 2 ounces of cheese, half a pound of potatoes, and 2 slices of bacon. To calculate the cost of each of these ingredients for the dish, you'll need to figure out how much of your purchase price your used portion works out to.
To calculate the eggs, you first figure out how much each egg is. So, you divide the $2.50 by 12 since there are 12 eggs in a dozen. You get:
$2.50 / 12 = $0.21.
You are using 3 eggs, so you multiply the cost per egg by 3. You get:
$0.21 * 3 = $0.63.
So, this is the cost for your eggs for one omelet dish.
For the cheese, since you are calculating the cost of ounces, you divide the cheese cost by 16 since there are 16 ounces in 1 pound. You get:
$5.00 / 16 = $0.31.
You are using 2 ounces, so you multiply by 2:
$0.31 * 2 = $0.62.
For the potatoes, you are using just half a pound. So you divide your cost of the potatoes by 20 since you have 20 half pounds in 10 pounds. You get:
$2.00 / 20 = $0.10.
For the bacon, you divide the cost of the bacon by the number of slices. You get:
$4.00 / 16 = $0.25.
You use 2 slices for your dish, so you multiply the $0.25 by 2:
$0.25 * 2 = $0.50.
| Ingredient | Cost in Dish |
|---|---|
| 3 Eggs | $0.63 |
| 2 Ounces Cheese | $0.62 |
| Half Pound Potatoes | $0.10 |
| 2 Slices Bacon | $0.50 |
