Question

If in a pasture, there are 28 horses and chickens and 80 legs, how many chickens and horses are there?.

Answer 1

• 16 chickens
• 12 horses

Explanation:

You have 28 horses and chickens with a total of 80 legs, and you want to know the number of each kind of animal.

Setup

Let h represent the number of horses. Then 28-h is the number of chickens, and the total number of legs is ...

4h +2(28-h) = 80

Solution

Simplifying the equation, we get ...

2h +56 = 80

h +28 = 40 . . . . . . . divide by 2

h = 12 . . . . . . . . . . subtract 28

28 -h = 16 . . . . . find the number of chickens

There are 16 chickens and 12 horses in the pasture.
