Example 3

Range of Optimality and 100% Rule

Answer:

If c = 7.5, the amount c changed is 7.5 - 6 = 1.5.

The maximum allowable increase is 12 - 6 = 6, so this

is a 1.5/6 = 25% change. If c = 6, the amount that c 2

changed is 9 - 6 = 3. The maximum allowable

decrease is 9 - 4.5 = 4.5, so this is a 3/4.5 = 66.7%

change. The sum of the change percentages is 25% +

66.7% = 91.7%. Because this does not exceed 100%,

the optimal solution would not change.
