Question

A group of 20 dogs are at the dog park. Fourteen of the dogs have an average weight of 45 pounds. The remaining dogs have an average weight of 20 pounds.

What is the average weight of all 20 dogs?

Answer 1

`(14*45+6*20)/(20)`

In short, the average weight of all 20 dogs is 37.5 pounds.

Answer 2

37.5 pounds if you multiply 45x14 which equals 630 and then 6x20 which equals 120 add it together to get 750 and then divide by the total number of dogs, 20 to get the average weight.
