Q:

# At 3% annual interest compounded monthly, how long will it take to double your money?

 A) 20.1 B) 21.1 C) 22.1 D) 23.1

Answer:   D) 23.1

Explanation:

At first glance it might seem that this problem cannot be solved because we do not have enough
information. It can be solved as long as you double whatever amount you start with. If we start with
$100, then P =$100 and FV = \$200.

FV=P(1+r/n)^nt
