Hello, I need some help with this precalculus question for my homework, please HW Q14

Given:
$20 invested at 12% compounded continuously for a period of 4 years.
So,
P = 20
r = 12% = 0.12
t = 4 years
We will use the following formula:
[tex]A=P*e^{rt}[/tex]Substitute with the given data:
[tex]A=20*e^{0.12*4}\approx32.321488[/tex]Rounding to the nearest cent
So, the answer will be:
After 4 years, the investment = $32.32
