Question

Qual o valor do capital que, se aplica por 8 meses a taxa de juros compostos de 60,10% a.a., rendera juros de r$ 2.355,00?

Answer 1

PV=?

n=8m= 8/12= 2/3ano

i=60,1%aa =0,601aa

J=2355

FV=PV+2355

PV= FV/(1+i)^n

PV= (PV+2355)/1,601^2/3

PV×1,601^2/3= PV+2355

PV×1,36855= PV+2355

1,36855PV=PV+2355

0,36855PV=2355

PV=2355÷0,36855

PV=6389,91
