I can't figure out how to do this problem. I added the numbers and divided by 5 and got 20.2 but the teacher marked it wrong. I have to turn it in corrected tomorrow.Thanks for any help you can provide.

The average weight of the first two dogs was 43 pounds.
The average weight of the next three dogs was 58 pounds.
What was the average weight of all the dogs?
:
Try it this way
Av = %282%2843%29%2B3%2858%29%29%2F5
Av = %2886+%2B+174%29%2F5
Av = 260%2F5
Av = 52 lbs
