Answer:
An increase in Price and decrease in Quantity.
Step-by-step explanation:
Please see the attached Decrease in Supply when Demand is Constant Diagram for further explanation:
Supply Curve is always upward because Supply and Price are directly proportional as shown in attached diagram as S .
Demand Curve is always downward because Demand and Price are inversely proportional as shown in attached diagram as D .
The point where Demand Curve and Supply curves meet each other or intersect each other is called Equilibrium as shown in the attached diagram as E. At this the point Quantity Demanded and Quantity Supplied are equal.
The point at which Equilibrium touches the price is called Equilibrium Price as shown in the attached Diagram as P. At this point the Quantity Demanded and Quantity Supplied are equal.
The Point at which Equilibrium touches the quantity is called Equilibrium Quantity as shown in the attached Diagram as Q. At this point the Quantity Demanded and Quantity Supplied are equal.
Since the Demand is constant D and Supply is decreasing, So when the Supply decreases it shifts towards its left side as shown in the attached diagram as S'.
After decrease in Supply the changes it brings a new Equilibrium point as E' at which Equilibrium Price rises to P' and Equilibrium Quantity falls to Q' as shown in the attached diagram. At this point the Quantity Demanded and Quantity Supplied are equal.
