If the coefficient for Activity 2 in the objective function changes to $400, then the objective function value (Assume that an Activity is a decision variable): will increase by $7, 500 will increase by $2, 750 will increase by $100 will remain the same can only be discovered by resolving the problem Variable Cells Constraints What is the allowable range of the right-hand-side for resource A(Assume that an Activity is a decision variable)? -infinity lessthanorequalto RHS_A lessthanorequalto 60 0 lessthanorequalto RHS_A lessthanorequalto 110 -infinity lessthanorequalto RHS_A lessthanorequalto 110 110 lessthanorequalto RHS_A lessthanorequalto 1600 0 lessthanorequalto RHS_A lessthanorequalto 160
