Graph out this situation using a single supply and demand diagram representing one firm

Graph out this situation using a single supply and demand diagram representing one firm.

Label the initial equilibrium price and quantity (P1, Q1);

Then demand increases, creating an excess demand.

The firm can either respond by increasing price along a stationary supply curve - label this equilibrium price and quantity with (P2, Q2); or by increasing supply - label this equilibrium price and quantity with (P3, Q3).

In your diagram, label the producer surplus areas under both equilibriums (P2, Q2) and (P3, Q3).
