Questão: Dada a taxa 5,6% a.m, a taxa anual seria de: 92,29% a.a. 67,20% a.a. 70,30% a.a. 97,16% a.a.

Vamos calcular a taxa anual a partir da taxa mensal de 5,6% ao mês: Taxa anual = ((1 + 0,056)^12 - 1) * 100 Taxa anual = (1,056^12 - 1) * 100 Taxa anual = (1,9229 - 1) * 100 Taxa anual = 0,9229 * 100 Taxa anual = 92,29% Portanto, a resposta correta é: 92,29% a.a.
