You can put this solution on YOUR website! There are originally 265 foxes and 104 rabbits on a particular game reserve.
The fox population grows at a rate of 36 foxes per year, and the rabbits increase at a rate of 65 rabbits per year.
Under these conditions, how long does it take for the number of rabbits to catch up with the number of foxes?
:
Let y = no. of yrs for them to be equal
:
Rabbits = Foxes
65y + 104 = 36y + 265
65y - 36y = 265 - 104
29y = 161
y = 161/29
y = 5.55 yrs
:
How many of each animal will be present at that time?
65(5.55) + 104 ~ 465 rabbits
36(1.55) + 265 ~ 465 foxes
