Answer:

0.06182 or 6.182%

Explanation:

The total interest rate over 14 years paid by First Simple Bank is given by:

[tex]I_S = 0.094*14 = 1.316[/tex]

The rate required by First Complex Bank, assuming compounded interest over 14 years, to match the interested paid by First Simple Bank is:

[tex]I_C = (1+r)^{14}-1=I_S\\(1+r)^{14}-1=1.316\\r=\sqrt[14]{2.316}-1\\ r=0.06182 = 6.182\%[/tex]

First Complex Bank should set an interest rate of 6.182%.
