Consider the relationship between monopoly pricing and price elasticity of demand. If demand is inelastic and a monopolist raises its price, total revenue would and total cost would , causing profit to . Therefore, a monopolist will produce a quantity at which the demand curve is inelastic. Use the purple segment (diamond symbols) to indicate the portion of the demand curve that is inelastic. (Hint: The answer is related to the marginal-revenue (MR) curve.) Then use the black point (plus symbol) to show the quantity and price that maximizes total revenue (TR).
