The per unit contribution decreasing by $5\%$ as sales effort increases introduces a non-linear relationship between the variables (sales effort and per unit contribution), making a linear programming model inappropriate for this situation. Linear programming assumes linearity in both the objective function and the constraints, which is not the case here.
