A monopolist faces the following demand curve, marginal revenue curve, total cost curve and marginal cost curve for its product:
Ad libitum [116K]

The total profit that is earned is 4512.5

<h3>How to solve for the profit that is earned</h3>

100 - q = 0

q = 100

Maximization is where q = 0

MR = mc

100 - q = 5

such that q = 95

Price would be  100 -0.5(95)

= 100 - 47.5

= 52.5

Profit earned would be

= 95*52.5 -5*95

= 4512.5
