Final answer:
A pure perfect competitor has the overall demand to itself because it is the only seller in a market.
Step-by-step explanation:
A pure perfect competitor has the overall demand to itself because it is the only seller in a market. A perfectly competitive firm is known as a price taker, meaning it accepts the prevailing equilibrium price in the market. It can sell all the output it wishes at the prevailing market price, as it faces a perfectly elastic demand curve.
