Problem

A company estimates that the price pp (in dollars) required to sell qq units of a product is given by p=120−2qp=120-2q. What quantity qq maximizes the company’s total revenue? a) q=60q=60 b) q=30q=30 c) q=15q=15 d) q=40q=40
Intuitive explanation

Revenue is the product of price and quantity: R=pqR = pq. Substitute the price equation to express revenue purely in terms of qq, then find where its derivative equals zero—that's the quantity that maximizes profit. This turns a real-world constraint into a straightforward calculus optimization problem.
