Step 1

Given;


\begin{gathered} P=7600 \\ r=(8.2)/(100)=0.082 \\ t=1 \end{gathered}

Step 2

A) she will owe


\begin{gathered} A=P(1+(r)/(n))^(nt) \\ A=7600(1+(0.082)/(12))^(12*1) \\ A=\text{ \$}8247.16 \end{gathered}

B) The effective annual rate is given as;


\begin{gathered} R=(1+(i)/(n))^n-1 \\ R=[(1+(0.082)/(12))^(12)-1]*100 \\ R=0.08515*100=8.515\text{\%} \\ R\approx8.52\text{\%} \end{gathered}
