More than one way to do this.\r

\n" ); document.write( "Carpenter, (3/2)r
\n" ); document.write( "Helper, r
\n" ); document.write( "Carpenter&Helper, 1/15
\n" ); document.write( "Unit is jobs per day.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Combined rate is their sum.\r
\n" ); document.write( "\n" ); document.write( "\"highlight_green%28%283%2F2%29r%2Br=1%2F15%29\"
\n" ); document.write( "Solve for r and find its reciprocal; and this is how many days the helper needs to do 1 job.
