He buys +1440%2A12+ pens
at +2.5%2F12+
----------------------------
+%28+2.5%2F12+%29%2A%28+1440%2A12+%29+=+2.5%2A1440+
+2.5%2A1440+=+.25%2A14400+ is his cost
------------------------------------
+.25%2A12%2A1440+-+.25%2A14400+ is his profit
+.25%2A1440%2A%28+12+-+10+%29+=+.25%2A2880+
+720+ dollars is his profit
