Question 333235
<font face="Garamond" size="+2">


I would say to myself, 20% of anything is one-fifth, so 20% of 25 oz is 5 oz.  If  I add 50 oz of water, I now have 75 oz of solution of which 5 oz is alcohol, so that is one part in 15, or *[tex \Large 6 \frac{2}{3}%].  That might not be how you would do it, or how your teacher wants it done though.  But it is the correct answer nonetheless.

*[tex \LARGE e^{i\pi} + 1 = 0]
My calculator said it, I believe it, that settles it
