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?
\n" ); document.write( "----
\n" ); document.write( "I guess the one cup of vinegar is 100% vinegar.
\n" ); document.write( "------
\n" ); document.write( "Equation:
\n" ); document.write( "100%*1 cup + 15%*3 cups = x%(1+3)cups
\n" ); document.write( "-----
\n" ); document.write( "Multiply thru by 100 to get:
\n" ); document.write( "100 + 15*3 = x + 3x
\n" ); document.write( "4x = 145
\n" ); document.write( "x = 36.25% (percent vinegar in the final mixture)
\n" ); document.write( "-------------
