Answer :
45 animals because 30/2 = 15
15 + 30 (of the dogs) = 45!
15 + 30 (of the dogs) = 45!
The shelter has 45 animals in total because there are fifteen cats cause there are half as many cats to dogs. So when you add the total number of cats to the total number of dogs you get the total number of animals being 45 . :) hope that helped
