The Widget industry is perfectly competitive. The lowest point on the long-run average cost curve of each of the identical widget producers is $4 and this minimum point occurs at an output of 1,000 widgets per month. When the optimal scale of a firm's plant is operated to produce 1,150 widgets per month, the short-run average cost of each firm is $5. The market demand curve for widgets is:

Qd= 140,000 -10,000P where Qd is the quantity of widgets demanded per month and P is the price of a widget.

The market supply curve is:

Qs= 80,000 + 5,000P, where Qs is the quantity of widgets supplied per month and P is the price of a widget.

If the market demand curve shifts to:
Qd= 150,000 -5,000P

What is the new equilibrium price and output in the short run for both the industry and each firm?
