Answer:
$18,726.11
Step-by-step explanation:
Lets use the compound interest formula provided to solve this:

<em>P = initial balance</em>
<em>r = interest rate (decimal)</em>
<em>n = number of times compounded annually</em>
<em>t = time</em>
<em />
First lets change 9% into a decimal:
9% ->
-> 0.09
Since the interest is compounded quarterly, we will use 4 for n. Lets plug in the values now:


<u>The balance after 5 years is $18,726.11</u>
