This study aims to analyze the problem solving skills of economic students in "linear programming" course. A Thirty students were involved in this descriptive study. Data collected by observation and analysis of student answers to each case given. This learning used a case about “linear programming” as a stimulus to explore student problem solving skills. The study showed that students use graph, simplex, transportation, and assignment methods to solve problems about “linear programming”. In addition, this study also showed that students are only able to use mathematical formulas in solving questions about “linear programming”. However, students are not able to represent "cases of linear programming" in the form of mathematical language. It showed that students have not been able to apply the concepts to solve “linear programming” problems that exist in everyday life. Therefore, learning about "linear programming" should be emphasize giving authentic cases about “linear programming” because it expected to be able to train students problem solving skills.
