Textbook Problem

** Producer's surplus** Find the producers surplus at market equilibrium for Problem 44.

** Consumer's surplus** The demand function for a product under pure competition is

(a) Find the market equilibrium.

(b) Find the consumer’s surplus at market equilibrium.

To determine

**To calculate:** The producer’s surplus at market equilibrium if the demand function of a product is provided by

Explanation

**Given Information:**

The demand function of a product is provided by

**Formula used:**

If the demand curve is

The producer’s surplus is provided by

According to the power rule of integrals,

**Calculation:**

Consider the demand function,

Now, at equilibrium point, the demand function and supply function must be equal.

Take square on both sides,

This gives the values
