Solved linear programming exercises 2

In this video I'm going to do an exercise in linear programming.

The statement of the problem that I will solve is the following:

"In a chicken farm a diet is given, to gain weight, with a minimum composition of 15 units of a substance and another 15 of a substance B. There are only two classes of compounds on the market: type X with a composition of one unit of A and 5 of B, and the other type, Y, with a composition of 5 units of A and one of B. The price of type X is 10 euros and type Y is 30 euros. What quantities of each type must be purchased to meet the needs at a minimum cost? "

Let us remember that the linear programming is optimizing, maximizing, or minimizing functions that are limited by certain constraints.

The steps to follow to solve a linear programming problem are the following:

1. Identify the unknowns.

2. Write the objective function

3. Write the constraints as inequalities

4. Make a graph with all the equations and inequalities and find the feasible solutions.

5. Calculate the optimal solution.

In the video we will see a practical example of solving linear programming problems. Also, if you are not sure you can continue practicing with problems of this type you can do the printable exercises with their solutions that I have left you on the web. Good luck in your studies!
