Plot the ratio of the actual to the optimal cost as a function of b, the ratio of the actual order quantity to the optimal order quantity for values of b between 0.25 and 2.0. If we order 25% more than the optimal quantity, what is the percentage increase in the total fixed ordering plus inventory carrying cost. You should be using equation (8.159) in this exercise.
