<PRE><B>Question 1199268</B>
Araceli,  d days  1 job
Chris, {{{(3/4)d}}}  days 1 job
Jay, {{{(2/3)(3/4)d}}} days 1 job


The three combined need  {{{36/13}}} days to do 1 job.

{{{(1/d+1/((3/4)d)+1/((2/3)(3/4)d))(36/13)=1}}}----------simplify and solve first for d.


STEPS POSSIBLE-----------

{{{1/d+4/(3d)+2/d=13/36}}}

{{{3d(1/d+4/(3d)+2/d)=3d(13/36)}}}

{{{3+4+6=13d/12}}}

{{{13=13d/12}}}

{{{1=d/12}}}

{{{highlight(d=12)}}}------------Time for Araceli, working alone.


You can use this to find time for Chris and for Jay.</PRE>
