Answer:
$26,851.54
Explanation:
Lets use the compound interest formula provided to solve this:
P = initial balance
r = interest rate (decimal)
n = number of times compounded annually
t = time
Our first step is to change 5.5% into a decimal:
5.5% ->
-> 0.055
Since the interest is compounded monthly, we will use 12 for n. Lets plug in the values now:
The ending balance after 18 years is $26,851.54
