Answer

Explanation:

Step1: Definir la fórmula de tasa de comisión

La tasa de comisión $r$ se calcula como $r=\frac{\text{Comisión}}{\text{Monto total de ventas}}\times100%$.

Step2: Sustituir valores

Dado que la comisión es $$31.29$ y el monto total de ventas de pasajes aéreos es $$208.60$, entonces $r = \frac{31.29}{208.60}\times100%$. Calculando $\frac{31.29}{208.60}\approx0.15$, y $0.15\times 100% = 15%$.

Answer:

B. 15%
