as far as me no, no such equashun...add % interest & add $ evree month
oenlee wae me no is rite short rogram tu loop...add 2 parts at eech step
start $ =100,000, 8% interest, add 100$/month, 9 yeers
#####

yu put in 110,800$, so end value almost 2* that
If oenlee us kood get 8%...but Obama insist all interest rates gotta be ZERO
