Answer:
![A=\$5003.2](https://img.qammunity.org/2020/formulas/mathematics/college/taujkot6o8nrur07nuo8h234t2tczm6sxz.png)
Explanation:
Use the exponential growth formula
![A = Pe ^ {rt}](https://img.qammunity.org/2020/formulas/mathematics/college/3o5v4lpo435jr0wx6h1cvxy6u3ukrpz9eg.png)
Where A is the final amount in the account, P is the initial amount, r is the growth rate and t is the time in years
In this problem
We know that
![P=4,200\\\\r=(3.5\%)/(100\%)= 0.035\\\\ t=5\ years](https://img.qammunity.org/2020/formulas/mathematics/college/dd2aoucc81f3bywjorngvrs76pfm7swbze.png)
So
![A = 4,200e^(0.035t)](https://img.qammunity.org/2020/formulas/mathematics/college/bgyl5wz8xudb3veiyb334ppvfxr59bjqvm.png)
Finally after 5 years the balance of the account is:
![A=\$5003.2](https://img.qammunity.org/2020/formulas/mathematics/college/taujkot6o8nrur07nuo8h234t2tczm6sxz.png)
