Consider the relationship between monopoly pricing and the price elasticity of demand. if demand is inelastic and a monopolist raises its price, quantity would fall by a percentage than the rise in price, causing profit to . therefore, a monopolist will produce a quantity at which the demand curve is elastic. 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).
