Question

Qual deve ser o rendimento obtido na aplicação de R$1.000,00 durante dois meses, no regime de juros compostos a taxa de 1%a.m.?

Answer 1

M = C.(1+i)^t
M = 1000.(1+0,01)²
M = 1000.(1,01)²
M = 100 . 1,0201
M = 1020,10

R$ 1.020,10

Answer 2

$C=1.000,00\\ n=2 meses\\ i=0,01\\\\M=C*(1+i)^n\\\\\\ M=1.000*(1+0,01)^2\to \\\\ M=1.000*(1,01)^2\to \\\\ M=1.000*1,0201\to\\\\ M=1.020,10\\\\\\\\\\ J=M-C\to\\\\ J=1.020,10-1000\to \\\\J=20,10$
