In perfect competition, each additional unit of output that a firm sells will yield a marginal revenue that is:
equal to average total.
costless than price.
equal to price.
greater than price.

Respuesta :

Answer:

The correct answer is equal to price.

Explanation:

A perfectly competitive firm is a price taker. This is because of the large number of firms, no single firm is able to influence the price. So each firm faces a horizontal demand curve. This horizontal line shows demand, marginal revenue, and average revenue.  

The price level is determined at the point where the marginal cost is equal to price. The marginal revenue is always equal to price because the price is fixed at a point, each output level is supplied at the same price.
