Ten dogs and cats were fed 56 biscuits. Each cat received 5 biscuits, and each dog - 6. How many

were dogs and how many were cats?
How many biscuits would be needed if all the animals were dogs?

## Solution

If only dogs were being fed, 106=60 biscuits would be needed. The extra 4 biscuits are required because a dog eats one more biscuit than a cat. This means there were 4 cats, and consequently, 6 dogs.

## Answer

6 dogs and 4 cats.
