Fifty-six biscuits are to be fed to 10 pets; each pet is either a cat or a dog. each dog is to get six biscuits, and each cat is to get five. how many dogs are there?
Answer: There are 6 dogs
Explanation:
Total number of biscuits = 56
Total number of Pets = 10
Now each dog is to be given 6 biscuits and each cat is to be given 5 biscuits.
Now if there are 6 dogs and each is to be given 6 biscuits and total biscuits given to 6 dogs = 6 x 6 =36
and there are 4 cats and each is to be given 5 biscuits and total biscuits given to 4 dogs = 4 x 5 =20
Therefore, total biscuits given to 6 dogs and 4 cats is 36+20= 56
