Verified step by step guidance

1. Understand the concept of market equilibrium: it occurs where the quantity demanded by consumers equals the quantity supplied by producers.
2. Look at the table and identify the quantities demanded and quantities supplied at different price levels.
3. Find the price at which the quantity demanded is exactly equal to the quantity supplied.
4. The equilibrium quantity of output is the quantity corresponding to this price where demand equals supply.
5. Ignore the lowest quantity demanded, the sum of all quantities, and the highest quantity supplied, as these do not define equilibrium.
