I thought it would be 2/3 of 116 = 77.3256

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.
