This paper deals with the role of non-mathematical knowledge in the use of mathematical models on problems in concrete contexts. For this, a praxeological model based on the anthropological theory of the didactic is used. From the model used for the calculation of Personal Income Tax, we obtained preliminary results that point out the indispensability of non-mathematical knowledge of the situation for the pertinent use of mathematical models.
