Question 613789
If 1.5 dogs can eat 1.5 lbs of food in 1.5 days. How many lbs of food can 16 dogs eat in 4 days?
--------------------------
# of pounds is directly related to # of dogs and to # of days.
----
lbs =  k*g*d
----
Solve for "k" using "1.5 dogs can eat 1.5 lbs of food in 1.5 days".
----
1.5 = k*1.5*1.5
1.5 = k*2.25
k = 2/3
-----
Equation:
lbs = (2/3)*g*d
------
lbs = (2/3)*16*4
lbs = (2/3)64 = 128/3 = 42 2/3
