+A+=+P%2A%28+1+%2B+r%2At+%29%0D%0A%7B%7B%7B+t+ = time in yrs
+P+ = amount owed
+A+ = amount owed plus interest
-----------------------------------
+100%2A%28+12t+%29+=+1200t+ = amount paid after +t+ yrs
+1200t+=+2520.74%2A%28+1+%2B+.1599t+%29+
+1200t+=+2520.74+%2B+403.066t+
+796.934t+=+2520.74+
+t+=+3.163+ yrs
and
+.163%2A12+=+1.96+ months
It takes 3 yrs and 2 months to pay off $2,520.74
