Question

an increase in the number of producers will:
a. increase the market supply only when market demand increases too.
b. increase the market supply, because market supply is the sum of all individual supply curves.
c. increase the market supply, because the price will rise,
d. increase the market supply only if each supplier has an identical supply curve.

Explanation:

Market supply is defined as the sum of the quantities supplied by all individual producers in a market. When the number of producers increases, there are more individual supply curves contributing to the total, which directly increases the overall market supply, regardless of demand shifts, price changes, or identical supply curves among suppliers.

Answer:

b. increase the market supply, because market supply is the sum of all individual supply curves.
