Answer:
V = $1213.03
Step-by-step explanation:
We can determine the amount of money after 15 years with the given formula:
[tex] V = Pe^{rt} [/tex] (1)
Where:
V: is the value of the account in t years =?
P: is the principal initially invested = $686
r: is the rate of interest = 3.8% = 3.8/100 = 0.038
t: is the time = 15 years
By substituting the above values into equation (1) we have:
[tex]V = Pe^{rt} = 686*e^{(0.038*15)} = 1213.03[/tex]
Therefore, the amount of money is $1213.03.
I hope it helps you!
