Remember:
\n" ); document.write( " $\"D%5B1%5D\"$ = drain 1, 8 days
\n" ); document.write( " $\"D%5B2%5D\"$ = drain 2, 4days
\n" ); document.write( "If work together,
\n" ); document.write( "= $\"%28D%5B1%5D%2BD%5B2%5D%29%2F2\"$
\n" ); document.write( "= $\"%288%2B4%29%2F2\"$
\n" ); document.write( "= $\"12%2F2\"$ = $\"6days\"$ ---------------> If 2 work together
