To analyze the change in consumer surplus due to the rightward shift of the supply curve, let's break down the components in the graph:

1. Consumer Surplus Definition: Consumer surplus is the area between the demand curve and the price level, up to the equilibrium quantity.

2. Initial and New Supply Curves:

   • The initial supply curve is $S_1$.
   • The supply curve shifts to the right to $S_2$, resulting in a lower equilibrium price and a higher equilibrium quantity.

3. Equilibrium Points:

   • Before the shift, the equilibrium point is where $S_1$ intersects $D_1$, at point C (price approximately $30).
   • After the shift, the new equilibrium is where $S_2$ intersects $D_1$, at point D (price approximately $20).

4. Consumer Surplus Areas:

   • Initial Consumer Surplus: Before the shift, consumer surplus is the area ABC.
   • New Consumer Surplus: After the shift, consumer surplus expands to the area ABCD.

Answer:

The rightward shift of the supply curve will cause consumer surplus to increase from area ABC to area ABCD.

Tip:

In economic graphs, consumer surplus is often represented as the area above the price level and below the demand curve, up to the point of equilibrium.
