Two expressions to be summed.
\n" ); document.write( "\"%281%2F4%292%2B%281%2F4%2B1%2F8%29t=1\"-----total of 1 job, Max for 2 hour and then he and helper for t hours.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Multiply both sides by 8, and then simplify,
\n" ); document.write( "\"4%2B%282%2B1%29t=8\"
\n" ); document.write( "\"4%2B3t=8\"
\n" ); document.write( "\"highlight%28t=4%2F3%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "1 hour 40 minutes
