Accessible description: The figure above indicates on the y-axis dollars per unit and on the x-axis the quantity in units. Depicted in the figure is a marginal revenue curve, which is equal to $16 per unit and the Marginal Cost Curve increases through points (14, 11), (17, 16) and (19, 22). Also depicted are a Total cost curve and average total cost curve, which are both u-shaped. Average Variable costs curve decreases through points (14, 11) and then increases through points (17, 12). The average total cost decreases through the point (17,23) and (19, 22) and then increases. f1q23g1.jpg Consider the perfectly competitive firm in the above figure.
