 Hmm not sure but why don’t you use 199 proof Everclear - math would be easier.

This is almost embarrassing to admit except I am so long away from algebra...  
I am tincturing using a new device which requires a minimum of 2 cups of liquid 
but 3 is better so that is what I am using.
The problem is:  if I combine 8oz of 40% ethanol (80 proof) with 8oz of 76% 
ethanol (153 proof) and then add 8oz of distilled water, what percentage of 
ethanol will the final 3 cups be?  

I'm blushing to even have to write this but I have to get this project done and 
the final amount of ethanol needs to be known.  I would really appreciate 
understanding how to get the final answer so I can just make adjustments going 
forward.
Thanks for any help you can give.PT
