Eric owns eleven animals. some of his animals are rabbits and some are chicken. if there are a total of 38 legs what is the number of chickens does eric have

Total Animals = 11

Total legs = 38

Assumed all the animals are chicken:

11 x 2 = 22 legs

Difference in legs:

38 - 22 = 16

The difference in legs between rabbits and chicken:

4 - 2 = 2

Number of rabbits = 16 : 2 = 8

Number of chicken = 11 - 8 = 3

Answer: There are 8 rabbits and 3 chickens.

Check:

(8 x 4) + (3 x 2) = 38 legs

He would have 3 chickens
