• Draw a picture of the scenario, if you can.
  • Step(1) Formulate the objective function.
  • Step(2) Reduce the objective function to One variable.
  • Step(3) Take the derivative of the function and find the critical value(s).
  • Step(4) Find the local max or min by either First derivative (for rational         fractions ) or Second derivative test (polynomials) and check the end points to locate the max or min.
