Question

There are multiple chickens and rabbits in a cage. There are 72 heads and 200 feet inside the cage. How many chickens and how many rabbits?

Answer 1

Given:
heads = 72
feet = 200
Chicken = c
Rabbit = r

c + r = 72
2c + 4r = 200

c = 72 - r

2c + 4r = 200
2(72-r) + 4r = 200
144 - 2r + 4r = 200
2r = 200 - 144
2r = 56
r = 56/2
r = 28


c = 72 - r
c = 72 - 28
c = 44

There are 44 chicken and 28 rabbits.
