Question

Calcule o capital inicial aproximado Que, no prazo de 20 meses ,a 8% ao mês produziu o montante de R$932.227,09

Answer 1

M = C.(1 + i) ͭ
932.227,09 = C. (1 + 0,08²⁰)
C.4,661 = 932.227,09
C = 932.227,09 ÷ 4,661
C ≈ 200.005,81 ← Capital Inicial R$ 200.005,81 ← Valor aproximado

Answer 2

M = C(1 + i%)^t
932.227,09= C(1+0,08)^20

932.227,09=C(1,08)^20

C= 932.227,09/4,661

C= R$ 200,005,81
