Answer:
200 450
Explanation:
As the demand and supply schedule is given at different prices
The supply given by the producers and the demand given by the location should be mentioned at different prices with different supply and demand
So as we can see that
At price of $25
The supply is 0 and the demand is 500
At price of $50
The supply is 200 and the demand is 450
At price of $100
The supply and the demand is 300 each
At price of $150
The supply is 400 and the demand is 250
At price of $200
The supply is 500 and the demand is 0
So at a price of $50, the supply is 200 and the demand is 450
Therefore, the first option is correct
