A monopolist is a single seller in the market, while a perfectly competitive firm is one of many sellers. A monopolist has the power to set prices, while a perfectly competitive firm is a price taker and must accept the market price. This difference in market structure leads to monopolists typically charging higher prices and producing less output compared to perfectly competitive firms.
Minimizing cost
when price>marginal cost
Demand = Price = Marginal Cost.
A perfectly competitive firm is considered a price taker because it has no control over the price of the goods or services it sells. In a perfectly competitive market, there are many buyers and sellers, and each firm's output is a small fraction of the total market supply, so individual firms must accept the market price set by supply and demand forces.
Total Cost
The supply curve for a perfectly competitive firm in the short run is typically upward sloping and relatively elastic. This means that as the price of the good or service increases, the firm is willing and able to produce more of it. However, the firm's ability to adjust its output is limited by its fixed inputs in the short run.
