You can put this solution on YOUR website!
Let $\"+x+\"$ = ounces of pure supergrow to be added
\n" ); document.write( " $\"+%28+.12%2A%28+32+-+x+%29+%2B+x+%29+%2F+32+=+.175+\"$
\n" ); document.write( " $\"+.12%2A%28+32+-+x+%29+%2B+x+=+5.6+\"$
\n" ); document.write( " $\"+3.84+-+.12x+%2B+x+=+5.6+\"$
\n" ); document.write( " $\"+.88x+=+1.76+\"$
\n" ); document.write( " $\"+x+=+2+\"$
\n" ); document.write( "He should add 2 ounces of pure supergrow
\n" ); document.write( "to the 12% solution
