The Maximization Linear Programming Problems. Define the unknowns. Write the objective function that needs to be maximized. Write the constraints. For the standard maximization linear programming problems, constraints are of the form: \(ax + by ≤ c\) Since the variables are non-negative, we include the constraints: \(x ≥ 0\); \(y ≥ 0\). The goal of a linear programming problems is to find a way to get the most, or least, of some quantity -- often profit or expenses. This quantity is called your objective. 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.
