The average salary for the 149 adults is
(their total income)/149 = x%2F149
given:
%288%2A10%5E6+%2B+x%29+%2F150+=+100020
8%2A10%5E6+%2B+x=+100020%2A150
x+=+15003000+-+8000000
x+=+7003000
This is the total salary for 149 people (not including millionaire)
7003000%2F149+=+47000
the average salary for the remaining 149 adults in that town is $47000
