A person places $686 in an investment account earning an annual rate of 3.8%, compounded continuously. Using the formula V = Pe^

kykrilka [37]

Answer:

V = $1213.03

Step-by-step explanation:

We can determine the amount of money after 15 years with the given formula:

$V = Pe^{rt}$ (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:

$V = Pe^{rt} = 686*e^{(0.038*15)} = 1213.03$

Therefore, the amount of money is $1213.03.

I hope it helps you!
