Final answer:
The 100% rule for simultaneous changes in objective function coefficients states that if the sum of the percentage changes exceeds 100%, the optimal solution of a linear programming problem will definitively change.
Step-by-step explanation:
The 100% rule for simultaneous changes in objective function coefficients states that if the sum of the percentage changes exceeds 100%, the optimal solution of a linear programming problem will definitively change.
If the sum of the percentage changes is 100% or less, the optimal solution may or may not change.
Therefore, the correct answer is a) True.
