Este é um problema de juros simples, que é calculado pela fórmula:
I = Prt
onde I são os juros, P é o principal, r é a taxa e t é o tempo.
Seja P o capital inicial er a taxa anual. Então, de acordo com as informações fornecidas, temos:
6600 = P + P \vezes r \vezes \frac{27}{12}
e
6600 + 0,0075P = P + P \vezes r \vezes \frac{28}{12}
Resolvendo essas duas equações simultaneamente, obtemos:
P = 5488.56548
e
r = 0,9
Portanto, o capital inicial foi de 5.488,57 um e a taxa anual foi de 9%.
