Answer:
$150, $200
Explanation:
A schedule that shows relationship between quantity supplied and quantity demanded is used to estimate the equilibrium quantity and price where there is a balance between the buyer's willingness to buy and the seller's willingness to sell.
Below this equilibrium point there is excess of quantity demanded over limited supply.
Above equilibrium there is excess supply and less demand.
According to the given schedule the equilibrium price is $100 where demand and supply are both 300 units.
The prices at which there are excess supply is given below
At $150 400 units is supplied against 250 units demanded
At $200 500 units are supplied against 0 units demanded
