2. When the sum of percentage does not exceed 100 percent for simultaneous change in functional constraint, it does not indicate _______________________________.

a. a change that is within the allowable range for the right-hand side does not mean the original solution is still optimal.

b. whether a change to a right-hand side leads to a change in the optimal solution.

c. each additional hour allocated yields an additional profit.

d. None of the answers is correct.
