Therefore, for all enterprises, the average return is equal to the price of the item.marginal income (marginal revenue)Is the amount of total revenue change resulting from the sales of each additional unit. The result illustrates a conclusion that applies only to competitive companies: Total revenue is PXQ, and P is fixed for competitive companies. Therefore, when Q increases by one unit, the total gain is increased by P $. For competitive enterprises, marginal income equals the price of an i
