The profit-maximizing rule is MC=MR, which applies to both monopolistically competitive and perfectly competitive markets. In monopolistically competitive markets, firms have some market power and can set prices slightly above marginal cost, but still face competition from other firms. In perfectly competitive markets, firms are price takers and must sell at the market price determined by the intersection of supply and demand, where MC=MR. Therefore, the rule MC=MR is applicable to both types of markets.
