Decision variables are the choices a decision-maker controls, directly affecting the outcome of the problem. In the context of minimizing interview costs in surveying, "the number of people to survey in each market segment" (A) is a decision variable because adjusting this number can directly influence the cost and effectiveness of the survey. The overall survey budget (B), total number surveyed (C), and number of people to conduct interviews (D) are constraints or outcomes, not decision variables.
