Question

There are 4 times as many chickens as ducks, there are 72 more chickens than ducks how many chickens and ducks are there

Answer 1

c = number of chickens

d = number of ducks

c = 4d because there are 4 times as many chickens as ducks

c = d+72 because there are 72 more chickens

4d = d+72 after using substitution

4d-d = 72

3d = 72

d = 72/3

d = 24

c = 4d = 4*24 = 96 ...or... c = d+72 = 24+72 = 96

Answer: There are 96 chickens and 24 ducks
