Question

There are 7 animals a farmer's field. Some are cows and some are chickens. The farmer counts 18 legs in all.

How many of each animal are in the field?

Answer 1

There are 2 cows and 5 chickens in the field.

Step-by-step explanation:

Let's assume that the number of cows is represented by 'C' and the number of chickens is represented by 'Ch'.

Since each cow has 4 legs and each chicken has 2 legs, we can create an equation based on the total number of legs: 4C + 2Ch = 18.

Now we can solve the equation by trial and error. By substituting different values, we find that C = 2 and Ch = 5 satisfies the equation. Therefore, there are 2 cows and 5 chickens in the field.
