A person places $6520 in an investment account earning an annual rate of 2.5%,
compounded continuously. Using the formula V = Pert, where V is the value of the
account in t years, P is the principal initially invested, e is the base of a nfitural
logarithm, and r is the rate of interest, determine the amount of money, to the nearest
cent, in the account after 3 years.

Given:

Principal value = $6520

Annual rate of interest = 2.5% compounded continuously.

Time = 3 years

To find:

The amount of money after three years.

Solution:

Formula for the value of the amount is:

[tex]V=Pe^{rt}[/tex]

Where V is the value of the account in t years, P is the principal initially invested, e is the base of a natural logarithm, and r is the rate of interest.

Putting [tex]P=6520,r=0.025,t=3[/tex], we get

[tex]V=6520e^{(0.025)(3)}[/tex]

[tex]V=6520e^{0.075}[/tex]

[tex]V=7027.80466[/tex]

[tex]V\approx 7027.80[/tex]

Therefore, the amount of money after three years is about $7027.80.
