Answer:
The fall in the price of iced coffee from $4.25 to $3.50 will cause demand to grow.
Explanation:
This is because the market demand curve for any good is downward sloping: the higher the price, the lower the quantity demanded, and the lower the price, the higher the quantity demanded.
So this fall in price will move the equilibrium quantity (the point where supply and demand meet) to move to a point on the demand curve that is below the previous point.
