<PRE><B>Question 720792</B>
One cup of vinegar is mixed with 3 cups of a solution that is 15% vinegar and 85% oil. what is the percent vinegar in the final mixture?
----
I guess the one cup of vinegar is 100% vinegar.
------
Equation:
100%*1 cup + 15%*3 cups = x%(1+3)cups
-----
Multiply thru by 100 to get:
100 + 15*3 = x + 3x
4x = 145
x = 36.25% (percent vinegar in the final mixture)
-------------
Cheers,
Stan H.
