Maximizing Profit in Linear Programming

The video tutorial by Professor Jacob Sich covers the basics of linear programming, focusing on understanding and graphing inequalities to solve problems related to maximizing profit. The tutorial begins with an introduction to the concepts of linear programming, followed by a detailed explanation of how to write and interpret inequalities. The professor then demonstrates how to graph these inequalities on a graph paper, emphasizing the importance of shading the correct regions. Finally, the tutorial concludes with a practical example of calculating maximum profit by testing different coordinates and using an objective function.
