Question 67066
If 30 men can plant 1000 trees in 9 days, how many days would it take for 36 men to set out 4400 trees?
--------------
Let number of days = "x".

You are told: (9 days)(30 men)=1000 trees
Then 1 day=[1000 t]/(270m)
---------
EQUATION:
(x days)(36 m) = 4400 t
x=[4400 t]/[36 man days]
Substitute for days to get:
x=[4400 t]/[36 m(1000 t)/(270m)]
Notice: m's and t's cancel and you get:
x= 4400*270/36000
x= 33
-----------
Number of days required for 36 men to plant 4400 trees is 33
