When maximizing profit in a linear programming problem, the allowable increase and allowable decrease columns in the sensitivity report make it possible to find the range over which the profitability does not change. True False Changing the objective function coefficients may or may not change the optimal solution, but it will always change the value of the objective function. True False According to the 100% rule for simultaneous changes in objective function coefficients, if the sum of the percentage changes exceeds 100%, the optimal solution definitely will change. True False If the coefficient for Activity 1 in the objective function changes to $50, then the objective function value (Assume that an Activity is a decision variable): will decrease by $450 is $0 will decrease by $2750 will remain the same can only be discovered by resolving the problem, solution will remain the same
