The first step in formulating an LP problem is

• graph the problem.

• perform a sensitivity analysis.

• identify the objective and the constraints.

• understand the managerial problem being faced.

• define the decision variables.

In labor planning formulation, how would you write the constraint that there are only 10 full-time tellers (labeled as T) available?

LP theory states that the optimal solution to any problem will lie at

• the origin.

• a corner point of the feasible region.

• the lowest point in the feasible region.

• none of the above
