To find the equilibrium price in a market, we look for the price at which the quantity supplied equals the quantity demanded.
From the table provided:
- At $10: Quantity Supplied = 1,000, Quantity Demanded = 2,500
- At $20: Quantity Supplied = 2,000, Quantity Demanded = 2,000 (Equilibrium)
- At $30: Quantity Supplied = 3,000, Quantity Demanded = 1,500
- At $40: Quantity Supplied = 4,000, Quantity Demanded = 1,000
The equilibrium occurs at a price of $20, where quantity supplied equals quantity demanded (2,000 units).
Thus, the answer is:
$20.
