A 25 � ounce solution is 20% alcohol . If 50 ounces of water added to it , what
percent of the new solution is alcohol?


20% of the 25 ounces is alcohol and the rest of the
25 ounces is water.

20% of the 25 ounces is 5 ounces, so 5 ounces of the 
25 ounces is alcohol and the other 20 ounces is water.

Now if we add 50 ounces of water to those 20 ounces,
there is 70 ounces of water, but still only 5 ounces 
of alcohol, so  or about 7.1% alcohol.
