Answer: Marginal revenue is equal to price times quantity
Step-by-step explanation:
A perfectly competitive market is a market where there's a large number of both the producers and the consumers have full and symmetric information.
In a perfectly competitive market, the marginal revenue is the same as price and the marginal revenue curve is the same as the demand curve facing sellers.
It should be noted that the statement that the marginal revenue is equal to price times quantity is incorrect. The total revenue is equal to price times quantity.
