Chapter Nine: Profit Maximization
faculty.metrostate.eduChapter 9: Profit Maximization Profit Maximization The basic assumption here is that firms are profit maximizing. Profit is defined as: Profit = Revenue – Costs Π(q) = R(q) – C(q) To maximize profits, take the derivative of the profit function with respect to q and set this equal to zero.

Chapter Nine: Profit Maximization
faculty.metrostate.eduThe profit maximizing quantity is where the revenue function and the cost function have the same slope and where the distance between them is maximized. The condition that the two functions have the same slope is the same as saying that marginal revenue equals marginal cost. Marginal Revenue Revenue is equal to price multiplied by quantity.
