The average age of all the animals at the animal rescue center is 5.4 months .
In the question ,
it is given that ,
at an animal rescue center .
percent of dogs that are present in the animal rescue = 80%
percent of cats that are present in the animal rescue = 20%
let suppose that there are total of 100 animals in the animal rescue .
So , the number of dogs = 80
and the number of cats = 20
also given that ,
the average age of dogs = 6 months
the average age of cats = 3 months .
So , the average age of all the animals can be calculated by
Average age = (80×6 + 20×3)/100
= (480 + 60)/100
= 540/100
= 5.4 months
Therefore , The average age of all the animals at the animal rescue center is 5.4 months .
At an animal rescue 80% of the animals are dogs and 20% of the animals are cats. If the average age of the dogs is six months and the average age of the cat is three months what is the average age of all the animals ?
