Consumer surplus change with price decrease Steps:

• Consumer surplus is the area below the demand curve and above the price line, up to the quantity demanded.
• At price P, initial surplus is the triangle from demand curve down to P.
• When price falls to P1, quantity demanded rises, expanding the surplus area to include the original triangle plus a new rectangle and triangle.
• Thus, consumer surplus increases overall.
