CALCULUS AB

To find the maximum of the function, take the derivative with respect to q2, and set the derivative equal to zero. Solving for q2 gives q2=30. Substitute into the budget constraint to get q1=20 (and U=600), and note that this is the same answer that you found using the Lagrangian method. (And, as with the Lagrangian method, to be sure that this ... ................
