To do this, they need to keep track of their marginal revenue and identify their profit maximization point. Marginal cost is the change in total cost that comes from making or producing one additional item. The demand function The first step in the process of coming up with a marginal revenue derivative is to estimate the demand function. The numerical answer is wrong so what mistake did I make? Now how does that work exactly? So 20 is the profit-maximizing quantity: to find the profit-maximizing price simply plug the value of Q into the inverse demand equation and solve for P.
