=E*

f. Use Excel and its Solver to formulate and solve the original nonlinear programming model directly. Compare with the answers obtained after completing part e.

g. Use calculus to find the value of x1 that maximizes 3x1 (x1 1)2

, the net profit from the first product. Also use calculus to find the value of x2 that maximizes 3x2 (x2 2)2

, the net profit from the second product. Show that these values satisfy the constraints for the nonlinear programming model.

Then compare these values with the answers obtained in parts e and f.
