Understand the definition of marginal cost: Marginal cost is the additional cost incurred from producing one more unit of output.
Recall that fixed costs do not change with the level of output, so total fixed cost is not part of marginal cost.
Recognize that sunk costs are past costs that cannot be recovered and do not affect current production decisions, so they are excluded from marginal cost.
Note that average total cost is the total cost divided by the number of units produced, which differs from marginal cost as it is not about the cost of one additional unit.
Conclude that marginal cost specifically refers to the additional variable cost incurred when increasing production by one unit.
