1. Use a fórmula de juros simples:
J = P \cdot i \cdot n
Substitua os valores conhecidos (\( J = 35105 \), \( i = 0.03 \), \( n = 6 \)):
35105 = P \cdot 0.03 \cdot 6
2. Resolva para \( P \):
P = \frac{35105}{0.03 \cdot 6}
P = \frac{35105}{0.18}
P = 195027.78
A quantia que deve ser aplicada é de R\$ 195027.78
