the change in the revenue that arises when one additional unit of a product is sold. The marginal revenue is calculated by dividing the change in the total revenue by the change in the quantity. In calculus terms, the marginal revenue is the first derivative of the total revenue function with respect
For example, the total cost of producing 100 units of a good is $200. The total cost of producing 101 units is $204. The average cost of producing 100 units is $2, or $200/100; however, the marginal cost for producing the 101st unit is $4, or ($204 – $200)/(101-100). The marginal revenue measures th
