5. What part of substitution into a formula do you not understand?
You are given ...
.. A = 5000
.. r = 4
.. n = 10
Conveniently, you are asked for V(10).
![V(10)=5000 * (1+ (4)/(100))^(10) \approx 7401.22](https://img.qammunity.org/2019/formulas/mathematics/middle-school/s9sdo7z9l1v8ajhsktjwrls5m8hdpq314d.png)
