I'm assuming that the 10 workers, working at
\n" ); document.write( "their normal rate would finish the job in exactly
\n" ); document.write( "8 days.
\n" ); document.write( "----------------------
\n" ); document.write( "The rate of working for 1 worker is:
\n" ); document.write( "[ 1/10 of the job ] / [ 8 days ] = [ 1 job ] / [ 80 days ]
\n" ); document.write( "This is also [ 1/80 of the job ] / [ 1 day ]
\n" ); document.write( "In 2 days, the fraction of the job that gets done is:
\n" ); document.write( "\"+2%2A%28+1%2F80+%29+=+1%2F40+\"
\n" ); document.write( "The leaves \"+39%2F40+\" of the job left
\n" ); document.write( "-----------------------------------
\n" ); document.write( "Now the rate has to be \"+%28+39%2F40+%29+%2F+2+=+39%2F80+\" jobs/days
\n" ); document.write( "Let \"+n+\" = the number of additional workers needed to
\n" ); document.write( "finish the job in 2 days
\n" ); document.write( "-----------------------------------
\n" ); document.write( "\"+%28+10+%2B+n+%29%2A%28+1%2F80+%29+=+39%2F80+\"
\n" ); document.write( "Multiply both sides by \"+80+\"
\n" ); document.write( "\"+10+%2B+n+=+39+\"
\n" ); document.write( "\"+n+=+29+\"
\n" ); document.write( "-------------------------------------
\n" ); document.write( "29 additional workers need to be added
\n" ); document.write( "-------------------------------------
\n" ); document.write( "check answer: there is a total of \"+39+\" workers to
\n" ); document.write( "do 39/40 of the job in \"+2+\" days
\n" ); document.write( "-------------------------------
\n" ); document.write( "Each worker will do \"+%281%2F39%29%2A%2839%2F40%29+=+1%2F40+\" of the job in \"+2+\" days
\n" ); document.write( "That is \"+1%2F80+\" of the job in 1 day
\n" ); document.write( "This agrees with my original calculation
\n" ); document.write( "-------------------------------
\n" ); document.write( "Definitely try to get another opinion on this!\r
