yarga [219]

Answer:

Deberá esperar 37.31 años para que esto ocurra.

Step-by-step explanation:

Este es un problema de interés simple.

La fórmula del interés simple viene dada por:

$E = P*I*t$

En el que E es la cantidad de interés ganado, P es el principal (la cantidad inicial de dinero), I es la tasa de interés (anual, como decimal) y t es el tiempo.

Después de t años, la cantidad total de dinero es:

$T = E + P$

5,36% mensual simple

Esto implica que $I = 0.0536$

Inversión se triplique ¿Cuánto tiempo deberá esperar para que esto ocurra?

Tiempo t para que la cantidad de interés sea lo doble de la cantidad inicial, o sea, $E = 2P$ .

$E = P*I*t$

$2P = P*I*t$

$It = 2$

$0.0536t = 2$

$t = \frac{2}{0.0536}$

$t = 37.31$

Deberá esperar 37.31 años para que esto ocurra.
