Ontario lottery has a promotion.  Buy $10.00 package worth of scratchers and receive a $3.00 scratcher for free. 

The payback percentage for the $10.00 package is 65.15%.  This percentage is independent of the payback for the free $3.00 scratcher.

The payback percentage for the $3.00 scratcher I want is 65.05%

What is the adjusted payback percentage?
