simple interst is when you earn interest from your principal but compound interest is when you earn interest from your principal as well as from your previous interest
$450.
Assuming the interest is NOT compound - 3 years !
Assuming that the 10 % stated is per year, the investment will earn 0.10 X 20000 = 2000 per year. The years required to earn 4000 will be 4000/2000 = 2.

You could probably do this easier but this is how I would do it. .05*4000 = 200+4000 = 4200*.05 = 210+4200 = 4410*.05 = 220.5+4410 = 4630.5 So you will end up with $4,630.50 your welcome
