\n" ); document.write( "--------------
\n" ); document.write( "paint = base + color
\n" ); document.write( "base = paint - color
\n" ); document.write( "given:
\n" ); document.write( "base / color = 15 / 1
\n" ); document.write( "( paint - color ) / color = 15/1
\n" ); document.write( " $\"+%28+1440+-+x+%29+%2F+x+=+15+%2F+1+\"$
