Answer:
[tex]A=\$5003.2[/tex]
Step-by-step explanation:
Use the exponential growth formula
[tex]A = Pe ^ {rt}[/tex]
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
[tex]P=4,200\\\\r=\frac{3.5\%}{100\%}= 0.035\\\\ t=5\ years[/tex]
So
[tex]A = 4,200e^{0.035t}[/tex]
Finally after 5 years the balance of the account is:
[tex]A=\$5003.2[/tex]
