How much would $100 invested at 8% interest compounded continuously be worth after 15 years?

Answers

The correct formula to use for continuous compounding is:
$A=Pe^(rt)$
where the exponential number e is the base of natural logarithms.
$A=100* e^{(0.08*15)=332.01$
So the amount after 15 years is $332.01

Answer:

$332.01 is correct via a p e x
