Linear Programming and Profit Maximization

This video tutorial demonstrates how to solve a linear programming problem using an example from Homer Tube Inc. It covers defining variables, writing the objective function, and setting constraints. The tutorial uses Desmos to graph the constraints and identify the feasible region. It concludes by evaluating the profit function to determine the optimal production strategy for maximizing profits.

What is the first step in solving a linear programming problem?

• Write the objective function

• Define the variables

• Graph the constraints

• Identify the vertices
