The profit-maximizing output is Q*=10,the point where marginal revenue equals marginal cost.At this output level, the slope of the profit curve is zero,and the slopes of the total revenue and total cost curves are equal. The profit per unit is $15,the difference between average revenue and average cost.Because 10 units are produced, total profit is $150.The profit-maximizing output is Q* = l0, the point where marginal revenue equals marginal cost. At this output level, the slope of the profit curve is zero, and the slopes of the total revenue and total cost curves are equal. The profit per unit is $15, the difference between average revenue and average cost. Because 10 units are produced, total profit is $150
