Answer:
c. the market equilibrium price of tickets to the concert exceeds $50
Step-by-step explanation:
Markets are at equilibrium when Market Demand = Market Supply and downward sloping demand curve, upward sloping supply curves intersect.
As mentioned : At Price = $50, demand of the product still exists after market clearing. This implies there is case of Excess Demand at prevalent price. This case happens when actual price < equilibrium price , because demand is more & supply less at lower prices
So: Actual price $50 is less than the market equilibrium price (which should be rather higher), equalising market demand & market supply - which should be rather higher.
