\n" ); document.write( "1st roofer DATA:
\n" ); document.write( "Time = x days/job ; Rate = 1/x job/day
\n" ); document.write( "-------------------
\n" ); document.write( "2nd roofer DATA:
\n" ); document.write( "Time = 3x days/job ; Rate = 1/3x job/day
\n" ); document.write( "---------------
\n" ); document.write( "Working-together DATA:
\n" ); document.write( "Time = 4 day/job ; Rate = 1/4 job/day
\n" ); document.write( "------------------
\n" ); document.write( "EQUATION:
\n" ); document.write( "rate + rate = together rate
