Answer:
Step-by-step explanation:To determine the total number of dogs and cats in the animal shelter, we need to find the ratio of the puppies to the total population.
Let's assume the total population of dogs and cats in the animal shelter is represented by "x". According to the given information, the 21 puppies make up 28% of the total population.
We can set up the following equation:
21 = 0.28x
To solve for x, we can divide both sides of the equation by 0.28:
x = 21 / 0.28
x ≈ 75
Therefore, there are approximately 75 dogs and cats in the animal shelter.
