It should be a positive 5 not a negative so the error was made at the end because u divide
Ok......... so ignore the pay part, that is not his pay but the 8% comission inclusive of the tax
The mean is the average.
Add all the number of pets and divide by how many people there were.

15/number of people
15/5
=3
Hope this helps :)
5+ 3 Well a times it would probably be 40
