+12%2A15+=+180++ months total
+746%2A180+=+134280+ = interest plus
principal paid over 180 months
--------------------------------
+i+%2B+P+=+134280+
+I+=+134280+-+P+
---------------------
+134280+-+P+=+P%2A%28+1+%2B+r%2F12+%29%5E%2812%2A15+%29+
+134280+-+P+=+P%2A%28+1+%2B+.066%2F12+%29%5E180+
+134280+=+P+%2B+P%2A1.0055%5E180+
+132480+=+P%2A%28+1+%2B+2.68394+%29+
+P+=+132480%2F3.68394+
+P+=+35961.5+
------------------------
Principal + down payment =
+35961.5+%2B+31248+=+67209.5+
The selling price was $67,209.50
-----------------------------------
In 15 yrs, they pay $134,280
