Then 38.66666 would be correct.

You will have 14.72 oz of water and 9.28 oz of alcohol in the total of 24 oz,now all you have to figure is the percentage. I figured that in my head as I never had algebra or Calc and barely passed math in high school.

    Thanks to you both.  Unfortunately this is the kind of thing I
    have been experiencing... widely divergent results.

    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.
