Answer:
a. the portion of its marginal cost curve that lies above the AVC
Explanation:
In short run, a perfectly competitive produces as long as its price is above its AVC, so revenues can cover total variable cost. If price is below AVC, the firm has to shut down. Since such a firm maximizes profit by equating Price with MC, this condition means that firm's supply curve is its MC curve lying above the (minimum point of) AVC curve.

Answer:
The equilibrium number of firms is 20.
Explanation:
Q = SH × b
    = 2,400 × (1/20)
    = 2,400 × 0.05
    = 120
Also given, Q = S / n
                 120 = 2,400 / n
                   n = 20
 
        
             
        
        
        
Answer:
Option C is the answer
Explanation:
The degree of operating leverage is measured by dividing the contribution margin by operating income. 
The degree of operating leverage (DOL) is the ratio of contribution margin to operating income. It measures how much the operating income of a company will change in response to a change in sales. A Companies that have higher proportion of fixed costs to variable cost will have greater levels of operating leverage.
