\n" ); document.write( "Eden DATA:
\n" ); document.write( "time = 12 hr/job ;rate=(1/12) job/hr
\n" ); document.write( "--------
\n" ); document.write( "Mimie DATA:
\n" ); document.write( "time = 9 hr/job ; rate =(1/9) job/hr
\n" ); document.write( "------------
\n" ); document.write( "Together DATA:
\n" ); document.write( "time = x hr/job ; rate = (1/x)job/hr\r
\n" ); document.write( "\n" ); document.write( "----------------------
\n" ); document.write( "EQUATION:
\n" ); document.write( "rate + rate = rate together
\n" ); document.write( "1/12 + 1/9 = 1/x
\n" ); document.write( "Multiply thru by 36x to get:
\n" ); document.write( "3x + 4x = 36
\n" ); document.write( "7x=36
\n" ); document.write( "x=36/7 hrs or x=5 hr 9 minutes
