Answer:
$332.82
Explanation:
We will use the compound interest formula provided to solve this:
![A=P(1+(r)/(n) )^(nt)](https://img.qammunity.org/2021/formulas/mathematics/college/fkrk7jnnltaq10r5wuio8ali7ua7712qxw.png)
P = initial balance
r = interest rate (decimal)
n = number of times compounded annually
t = time
First, we change 3.4% into a decimal:
3.4% ->
-> 0.034
Since the interest is compounded monthly, we will use 12 for n. Lets plug in the values now:
![A=200(1+(0.034)/(12))^(12(15))](https://img.qammunity.org/2021/formulas/mathematics/college/5ifxoam0o197bfa0yfsnnfbi481opp6vra.png)
![A=332.82](https://img.qammunity.org/2021/formulas/mathematics/college/l5crpyknjx53lnltbxno5s76i5cqp0c154.png)
Your balance after 15 years will be $332.82
