**bobpursley**, Sunday, March 8, 2009 at 1:30pmConvert the rates to work/mandays or work/womandays, etc.

So rate1=job/12*15*8 manhours

rate2=job/12*24*8 femalehours

rate2=job/12*36*8 boyhours.

Finally, the equation is

9/4 job = Xmen*6hrs/day*30days*rate1+ 12women*30days*6hrs/day*rate2 + 6 boys*30days*6hrs/day *rate3

solve for Xmen.
