Question

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

Answer 1

Answer:

 Investment amount after 9 years = 14715.12$

Explanation:

 It is given to use continuous change function, $A(t) = Pe^{rt}$

Here P = Principal = 10500$

          r = Rate of increase = 0.0375

          t = Number of years = 9

  $A(t) = Pe^{rt}\\ \\ A(t) = 10500*e^{0.0375*9}=14715.12$

 So, investment amount after 9 years = 14715.12$
