The easier formula for continuously compounded interest is [tex]A(t)=Pe^{rt}[/tex] where A(t) is the amount after all the compounding is done, P is the initial investment, r is the interest rate expressed as a decimal, and t is the time in years. Our formula then is filled in accordingly where P = 200, r = .05 and t = 9. [tex]A(t)=200e^{.05*9}[/tex] and [tex]A(t)=200e^{.45}[/tex]. e is Euler's number and there is a button on your calculator for it. If you hit 2nd and the ln button you get "e^ " on your display. Enter .45 as your exponent and then multiply that by 200. That gives us a value of $313.67 (your answer is $313.37...did you type the choice incorrectly, maybe?)
The answer is closest to $313.37 (B)
The formula we will use is A = P*e^rt Where A is amount, P is principal, r is rate, n is the number of years and t is the compounded period.
Amount = ?, P = $200, R = 5%, T = 9
A = P*e^rt
A = $200 x e^(0.05*9)
A = $200 x e^(0.45)
A = $200 x 1.56831218549
A = 313.662437098
A = $313.67
Thus, the worth of the $200 invested after 9 years is $313.67.
