Calculate the rate of return that Santander Bank grants to Mr. Patricio, if the latter invests $335,000 pesos for a period of 5 years, and receives interest in the amount of $170,000 at the end of the term.

1. Identificar los valores iniciales:
P = 335,000
I = 170,000
t = 5
2. Usar la fórmula de la tasa de interés simple:
r = \frac{I}{{P \cdot t}}
3. Sustituir los valores en la fórmula:
r = \frac{170,000}{{335,000 \cdot 5}}
4. Calcular el valor de \( r \):
r = \frac{170,000}{1,675,000} = 0.1015
5. Convertir la tasa de decimal a porcentaje:
r = 0.1015 = 10.15\%

\textbf{Respuesta: } 10.15\%
