4. Suppose the supply of apples sharply increases because of perfect weather conditions throughout the growing season. Assuming no change in demand, explain the effect on the equilibrium price and quantity of apples. Explain why the quantity demanded increases even though demand does not change.

Apples supply increase imply new equilibrium at lower price, higher quantity. Demand downwards expansion on the curve itself is due to lower price.

Explanation:

Market is at equilibrium where Market Demand = Market Supply, & downward sloping  demand curve intersects upward sloping demand curve.

If supply of apples increase & supply curve shifts rightwards, there is Excess Supply at previous equilibrium. Excess Supply creates competition among sellers, reduces new market price.

At lower price, demand expands & supply contratcs. New Equilibrium quantity is higher where new (rightwards shifted) supply curve intersects demand curve.

Quantity demanded increases (expands - downwards movement on demand curve) due to lower price, despite of no change in demand.
