$640, 3%, 2 years
show work too

It's 38.40 (:

How do you find out? well first you're going to want to multiply the percentage by the years so, 

2 x 0.3 = 0.6

Then you're going to want to times the NEW percentage by the money made so,

640 x 0.6 = 3.84

All you want to do now is just move the decimal over one then add a zero

So, 38.40 is the answer! (:
