# of days is directly related to # of deer and inversely related
to # of cheetas.
------
Equation:
D = k*d/c
----
Solve for "k" using "100 cheetas kill 80 deer in 60 days"
60 = k*80/100
60 = k*4/5
k = 15*5 = 75
------
Equation:
D = 75*d/c
In how many day 50 cheetah kill 40 deer?
D = 75*40/50
D = 75(4/5)
Answer:: D = 60 days
