163 a certain pet store has only cats and dogs. the ratio of the number of cats to the number of dogs in the pet store is 2: 3. 1 4 of the cats and 1 2 of the dogs wear collars. if 48 animals wear collars, what is the total number of animals in the pet store?

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
