Answer:
Price; marginal cost; cost minimizing; output; Cost of production or cost of inputs involved in production
Step-by-step explanation:
In perfect competition a firm is in equilibrium when its marginal cost of production is equal to the price of its product. The firm will be able to maximize profit or minimize cost at this point.
The demand curve is a horizontal line, which means demand is perfectly elastic. A change in the price will cause the demand to become zero.
The cost mentioned here is the cost incurred to employ inputs in the process of production, which is an explicit cost.
