Se dispone de 800 000 para invertir. Una cuenta paga el 18% de interés anual, y otra paga el 21%. ¿Cuánto debe invertirse en cad
Genrish500 [490]

Se debe depositar $ 600 000 en la cuenta con 18 % de interés <em>anual</em> y $ 200 000 en la cuenta con 21 % de interés <em>anual</em> para recibir $ 150 000 en intereses.

<h3>¿Cuánto se debe invertir en cada cuenta para alcanzar las ganancias deseadas en un período dado?</h3>

En este problema tenemos un depósito repartido en dos cuentas, que adquiere ganancias de manera <em>continua</em> en el tiempo. En consecuencia, tenemos por interés compuesto la siguiente ecuación a resolver:

x · (18/100) + (800 000 - x) · (21/100) = 150 000

168 000 - (3/100) · x = 150 000

(3/100) · x = 18 000

x = 600 000

Se debe depositar $ 600 000 en la cuenta con 18 % de interés <em>anual</em> y $ 200 000 en la cuenta con 21 % de interés <em>anual</em> para recibir $ 150 000 en intereses.
