The answer should depend on how much of some decision variables you choose. Your options for how much will be limited by constraints stated in the problem.
You may have constraints like "you can't spend more than $1000" or "you mus't ship at least 50 tons of product C". These are limits but don't necessarily reflect your employer's top priorities; don't mistake these for suggestions that you minimize costs or maximize production.
