Answer:

18 cool cats

Step-by-step explanation:

Answer:

B. 18

Step-by-step explanation:

A cat has 4 paws.

120/4 = 30

Since there are 120 paws, there are 30 cats.

The 30 cats are divided in the ratio of 2 uncool cats for every 3 cool cats.

There are 2x uncool cats and 3x cool cats.

2x + 3x = 30

5x = 30

x = 6

3x = 3(6) = 18

Answer: 18 cool cats
