Example: For example, the total cost of producing one pen is $5 and the total cost of producing two pens is $9, then the marginal cost of expanding output by one unit is $4 only (9 - 5 = 4).t is the difference between the total cost of the 6th unit and the total cost of the, 5th unit and so forth. Marginal Cost is governed only by variable cost which changes with changes in output. Marginal cost which is really an incremental cost can be expressed in symbols.

It is the fact that it contains yeast (that produce CO2 that get caught in a developed gluten matrix) that has allowed it to leaven bread for thousands of years.y sourdough bread recipe is to mix 1 cup of sourdough starter with 1 cup of water.
