Samuel invested $28,000 in an account paying an interest rate of 5% compounded continuously. Assuming no deposits or withdrawals are made, how much money, to the nearest dollar, would be in the account after 5 years?

Respuesta :

Answer:

$35,953 would be in the account after 5 years.

Step-by-step explanation:

The amount of money earned in interest which is compound continuosly after t years is given by the following equation:

[tex]A(t) = Pe^{rt}[/tex]

In which A(t) is the amount of money after t years, P is the principal(initial deposit) and r is the interest rate, as a decimal.

Samuel invested $28,000 in an account paying an interest rate of 5% compounded continuously.

This means that [tex]P = 28000, r = 0.05[/tex]

So

[tex]A(t) = Pe^{rt}[/tex]

[tex]A(t) = 28000e^{0.05t}[/tex]

How much money, to the nearest dollar, would be in the account after 5 years?

This is A(5)

[tex]A(t) = 28000e^{0.05t}[/tex]

[tex]A(5) = 28000e^{0.05*5} = 35952.7[/tex]

Rounding up to the nearest dollar

$35,953 would be in the account after 5 years.
