help a girl out ?? i'm not sure how to do the equation .

Answer:
Investment amount after 9 years = 14715.12$
Explanation:
It is given to use continuous change function, [tex]A(t) = Pe^{rt}[/tex]
Here P = Principal = 10500$
r = Rate of increase = 0.0375
t = Number of years = 9
[tex]A(t) = Pe^{rt}\\ \\ A(t) = 10500*e^{0.0375*9}=14715.12[/tex]
So, investment amount after 9 years = 14715.12$
