Answer
$59.83
Work Step by Step
We know the following equation:
$$A=P(1+ \frac{r}{n})^{nt}$$
Where:
P is the principal.
A is the amount of interest.
r is the rate, expressed as a decimal.
t is the time, in years.
n is the number of times the interest is compounded per year.
Thus, we obtain:
$$A=50(1+ \frac{.06}{12})^{12*3}\\ A= 59.83$$
