Total revenue is = Price x Quantity. For instance, if the demand curve was Q = 100 - P, find the inverse demand (P = 100 - Q). Total Revenue = 100Q-Q^2Therefore marginal revenue is the derivative of 100Q - Q^2.MR = 100 - 2Q (thus twice the negative slope).In short: inverse demand x Q, find the derivative.Source (s):Microeconomic Theory Class.LCM stands for Least Common Multiple.
