Some applications of graphical and simplex methods for solving linear programming problems

The paper presents some applications of the theory of mathematical programming in economics. In particular, when finding the extremum of multivariable functions with given multidimensional constraints, mathematical programming methods are used. The problem of using raw materials, the task of compiling a diet are also considered. In addition, the idea of the simplex method, the algorithm of the simplex method and the solution of examples using the simplex method are considered.
