Answer:

D. $674.68

Step-by-step explanation:

We will use the well known equation for compound interest

$A = P(1 + \frac{r}{n})^{nt}$

Where

$A$ is the final total
$P$ is the principal amount (starting total)
$r$ is the interest rate as a decimal
$n$ is the number of times the interest is compounded each year
$t$ the number of years

Plugging in what we know from the question:

$A = 500(1+\frac{0.03}{12})^{12 \times 10}\\A = 500(1.34935355)\\A = 674.68$

So the answer is D.

Hope this helps!
