## Question:

1. A firm has a demand function {eq}P = 100 - 5Q {/eq} and a cost function: {eq}AC=MC=20 {/eq}

a. What price, quantity, and profit occur if this a purely competitive market?

b. Determine the optimal price, quantity, and economic profit for the firm if it is a pure monopolist.

c. Determine the quantity and price that maximize revenue for the monopolist.

## Profit Maximization:

The strategic planning of firms in the employment of factors and the determination of price and output based on their costs to obtain the greatest profits possible is referred to as profit maximization.
