The key to this problem is:
\n" ); document.write( "(Dawn's rate of stuffing) + (Brother's rate of stuffing)
\n" ); document.write( "= (their rate stuffing together)
\n" ); document.write( "The rates are in units of (large party packs)/hour
\n" ); document.write( "Dawn's rate = \"1%2F6\"
\n" ); document.write( "Let \"b\" = Brother's rate of stuffing
\n" ); document.write( "given:
\n" ); document.write( "\"1%2F6+%2B+b+=+1%2F4\"
\n" ); document.write( "\"b+=+1%2F4+-+1%2F6\"
\n" ); document.write( "Multiply both sides by \"12\"
\n" ); document.write( "\"12b+=+3+-+2\"
\n" ); document.write( "\"b+=+1%2F12\"
\n" ); document.write( "The brother stuffs 1 party pack in 12 hrs working alone\r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
\n" );
