# Finding optimal output level

Firm PQR produces a product 'Alpha' under perfect competition market conditions. The cost function for the firm is:

TC = 1500 + 200Q + Q^2

The market supply and demand equations for the product 'Alpha' in the perfect competition market are:

QS = 40,000 + 60 P

QD = 80,000- 40 P

Based on the information given above, calculate:

1. The profit maximizing output for PQR.

2. The economic profits earned by PQR.

3. Is the industry for product 'Alpha' in equilibrium?

#### Solution Preview

1. The profit maximizing output for PQR.

Qs=40000+60P

QD=80000-40P

For equilibrium, Put Qs=QD

40000+60P=80000-40P

100P=40000

P=400

Each firm is a price taker in perfectly competitive environment. So, PQR will also sell its output at ...

#### Solution Summary

Solution describes the steps to find out profit maximizing output and economic profits of a perfectly competitive firm.
