ANSWER


\text{\$13,763.45}

Step-by-step explanation

We want to find the amount she will have after 5 years.

To do this, we apply the compound interest formula:


A=P(1+(r)/(n))^(nt)

From the question:


\begin{gathered} P=\text{ \$8000} \\ r=11\text{ \%= 0.11} \\ n=4 \\ t=5 \end{gathered}

n is 4 because there are 4 quarters in a year.

Therefore, we have that in 5 years, the amount she will have is:


\begin{gathered} A=8000(1+(0.11)/(4))^((4\cdot5)) \\ A=8000(1+0.0275)^(20)=8000(1.0275)^(20) \\ A\approx\text{ \$13,763.45} \end{gathered}

That is how much she will have in 5 years.
