Answer: maximize return on investment
Step-by-step explanation:
Linear programming is an optimization technique that is used for a system of linear constraints and an objective function that helps in defining the quantity that is to be optimized.
It is used for sure solving complex problems in businesss whereby deciding of the quantities f variables to use in achieving profit maximization or cost minimization is difficult.
Therefore, linear programming approach is usually used by managers involved in portfolio selection to maximize return on investment.
