The pet store groomed 32 pets on Monday. If the number of dogs groomed was three times as many as the number of cats, how many cats were groomed on Monday?

Let's set up an equation, with x representing the number of cats.
Since there were three times as many dogs as cats, then 3x = the number of\u00A0dogs.
Since the total number of animals groomed was 32, set up the following equation:
x + 3x = 32
4x = 32
x = 8 cats
