You can put this solution on YOUR website!
So, in 6 quarts, we have 60% of alcohol. We can say we have 3.6 quarts of alcohol. We must stop adding water when the ratio $\"3.6%2Fq+=+40%2F100\"$ , where q is the total number of quarts. \r
\n" ); document.write( "\n" ); document.write( "Solve for q:\r
\n" ); document.write( "\n" ); document.write( " $\"3.6%2Fq+=+40%2F100\"$
\n" ); document.write( " $\"3.6+=+40q%2F100\"$
\n" ); document.write( " $\"360+=+40q\"$
\n" ); document.write( " $\"q+=+9\"$ \r
\n" ); document.write( "\n" ); document.write( "Therefore, we must add 9 - 6 = 3 quarts of water. \n" ); document.write( "

\n" );
