Question

determinar o capital que, aplicado a taxa de 21.5% am , durante 4 meses produz, juro simples de R$62.178,00.

Answer 1

Capital de R$124.356,00.

J = C . i . t

J = R$62.178,00

i = 21,5% = 21,5/100 = 0,215 a.m.

t = 4 meses

62.178 = C . 0,215 . 4

62.178 = 0,5C

0,5C = 62.178

C = 62.178/0,5

C = R$124.356,00
