Answer:
yes!
Explanation:
yes this is a proportional relationship because if you take a look at each dry dog food to the wet dog food ratio the key component you are trying to find is the basic 1:x ratio and the x would be 3 in this case because if you see, the dry dog food is 3 times as many as the wet dog food in every single category so therefore yes this is proportional.
