60 months × $425.00= $2550.00 = what's my iterest rate? =

The truth is I was trying to figure out the interest rates on a car loan and this page poped up I really didn't realize this was for students in tell you wanted me to show my work! I'm 40 and if I don't know the answer by now I don't I never will but that...

I was hoping to using this as my a example could you show me how to get to the answer. I'm horrible at math.
