This article aims to present and analyze a task wich culminates in decision making in face of economic and financial situations, and involves a uniform series of payments. The assignment, made up of twelve items, was developed with eleven undergraduates of the Mathematics Course of the Universidade Federal de Santa Maria (RS) enrolled in the Financial Mathematics curriculum component. Based on the assumptions of School Financial Education and the records of semiotic representation, the data production adopted a qualitative approach, following the principles of the three phases that make up the content analysis. Therefore, we consider three categories: socio-cultural, economic-financial and behavioral. Through the inferences we found, among the results, arguments mainly linked to economic and financial aspects supported by justifications related to the non-commitment of the monthly budget and the maintenance of a reserve fund for eventual need; we also observed the option of maintaining a savings income while installments for the purchase of a good are paid monthly. While the sociocultural aspect was not identified in any of the analyzed items, the behavioral aspect was evidenced only when the choices were about the most easy as the least effort. In addition, we emphasize that the arguments of the undergraduates mobilized records of representation in natural language, numeric, symbolic and tabular algebraic.
