If demand increased by 100 units at each price level, and the government set a price ceiling of $40, then there will be

no surplus or shortage

Explanation:

Equilibrium price is the price at which quantity demand equal quantity supplied. Above equilibrium price there is a surplus - quantity supplied exceeds quantity demanded.

Below equilibrium price there is a shortage - quantity demanded exceeds quantity supplied

If demamd increases by 100, new equilibrium is 40

Thus, ceiling price equal equilibrium

Price ceiling is when the government or an agency of the government sets the maximum price for a product. It is binding when it is set below equilibrium price.
