Answer:
B. Marginal cost is the money paid for producing one more unit of a good. Marginal revenue is the money made from selling one more unit of a good.
Step-by-step explanation:
Comparing marginal cost and marginal revenue, we can say that;
The extra money incurred for producing one more unit of a good is called marginal cost. Since the number of goods produced has increased by a unit, then the variable cost of production would increase.
The amount of money realised after the sale of the extra unit produced is called the marginal revenue.
Thus marginal cost is the money paid for producing one more unit of a good, while marginal revenue is the money made from selling one more unit of a good.
