Question

Quizplus · Accepted Answer

The marginal cost refers to the cost of consuming one additional unit of a good or service. In the context of an all-you-can-eat sushi special for a fixed price of $20, the cost of consuming each additional piece of sushi (including the 10th piece) beyond the initial payment is effectively zero, as the initial payment covers all subsequent consumption.
