a first faces the demand curve, Q=180-5p, and has the
cost equation, c=100+24Q. what is the equation for the firm's
marginal revenue?
Answer
Inverting demand curve to inverse demand curve
Q=180-5P
5P=180-Q
P=36-0.2Q
total revenue =P*Q
=(36-0.2Q)*Q
TR=36Q-0.2Q^2
marginal revenue is the change in total revenue. a change in function found by differentiation.
MR=dTR/dQ=36-0.4Q ....... the first differential of TR function concerning Q.
MR=36-0.4Q
the marginal revenue function is
MR=36-0.4Q

1. (25 points) Suppose that a monopolist faces the inverse demand curve: P 100-Q and produces goods at a marginal cost of $5. Finally assume that the firm incurs no fixed costs A. Suppose the monopolist lowers the price from $90 to $89. Explain why the firm's marginal revenue is less than the price of the 11th unit sold, $89 (do not answer this question by providing a mathematical equation). B. At what price will the monopolist maximize its profit?...
