Answer:
A surplus (or excess demand) of about 8 units
Explanation:
The picture attached shows the diagram necessary for the question which is part of the question. Solution is given below;
At the above ceiling at price of 40$
Quantity supplied will be 16
Quantity demanded will be 24
So when demand is more than supply than there will be a shortage in quantity by (24-16) 8 units.
When there is demand more than supply than it is an excess demand.
So surplus or excess demand by 8 units.
