80% of the dogs are small dogs and 20% of the dogs are large dogs. If the average weight of the small dogs is 12 pounds and the average weight of the large dogs is 60 pounds, what is the average weight of all the dogs?

@AlexanderAL,
The easiest way to do this is to calculate the weight of 100 dogs.

Can you do that?
