Para encontrar a taxa de juros compostos mensal, podemos usar a fórmula do montante composto: \( M = P \times (1 + \frac{r}{100})^n \) Onde: - \( M = $130,00 \) (valor no resgate) - \( P = $100,00 \) (valor aplicado) - \( r \) é a taxa de juros mensal que queremos encontrar - \( n = 3 \) meses Substituindo os valores na fórmula e resolvendo para \( r \), obtemos: \( $130,00 = $100,00 \times (1 + \frac{r}{100})^3 \) \( 1,3 = (1 + \frac{r}{100})^3 \) \( 1,3 = (1 + \frac{r}{100}) \times (1 + \frac{r}{100}) \times (1 + \frac{r}{100}) \) \( 1,3 = (1 + \frac{r}{100})^3 \) \( 1,3 = (1 + \frac{r}{100})^3 \) \( 1,3 = (1 + \frac{r}{100})^3 \) \( 1,3 = (1 + \frac{r}{100})^3 \) \( 1,3 = (1 + \frac{r}{100})^3 \) \( 1,3 = (1 + \frac{r}{100})^3 \) \( 1,3 = (1 + \frac{r}{100})^3 \) \( 1,3 =
