Answer:
98 total animals
Explanation:
For every 5 dogs, there are 2 cats.
For every 10 dogs, there are 4 cats.
For every 15 dogs, there are 6 cats.
Hopefully you can see the pattern by looking at dogs and cats.
So for 70 dogs, 70 / 5 = 14
So you multiply the amount of dogs by 14 to get 70, but you also have to do the same with cats.
2 cats * 14 = 28 cats.
70 dogs + 28 cats = 98 total animals.
