Question

preciso do cálculo... ​

Answer 1

M = C . (1+i)

$20450.00 = 8000.00 \times {(1 + i)}^{24} \\ \frac{20450.00}{8000.00} = {(1 + i)}^{24} \\ 2.55625 = {(1 + i)}^{24} \\ \sqrt[24]{2.55625} = 1 + i \\ \sqrt[24]{2.55625} - 1 = i \\ 1.03988 - 1 = i \\ i = 0.03988 \\ i = 3.99\%$

arredondando, 4%.
