Question

Qual a capital que aplicado à taxa composta de 2%a.m durante um trimestre gera montante igual a R$225.000,00?

Answer 1

M=c(1+i)^n

255.000=c(1+0,02)³
225.000=1,061208c
C=225.000/1,061208
c=212.022,52 R$  

Answer 2

C×1,02×1,02×1,02 = 225.000
C × 1,061 =225.000
C = 225.000 / 1,061
C = 212.022,52
