The debt is paid in:
+200%2F12+=+50%2F3+ weeks
--------------------------
It takes
+60%2F12+=+5+ weeks to pay off $60
+50%2F3+-+5+=+50%2F3+-+15%2F3+
+35%2F3+=+11.667+
-------------------
Let +A+ = amount owed
Let +w+ = weeks that debt is paid
--------------------------------
+A+=+200+-+12w+
+A+%3C+60+
+200+-12w+%3C+60+
+12w+%3E+200+-+60+
+12w+%3E+140+
+w+%3E+35%2F3+
+w+%3E+11.667+
You will owe less than $60 when you
are 2/3 of the way through the 12th week
