Answer to Question 1

To determine the firm's profit, it is essential to determine the equilibrium price that the firm faces. At equilibrium QD = QS or, 650 - 25P = 200 + 20P or, 450 = 45P or, P = 10.
Profits = Total revenues - Total cost
= Price  Quantity - Average total cost  Quantity
= 10  20 - 6  20
= 200 - 120
= 80
