Salary:

Answer 1

check your typing

Is that supposed to say $8,000 ?

Answer 2

yes it is

Answer 3

in x years since 1985, the salary is

s(x) = 8000+600x

so, plug in x = 2012-1985

Answer 4

This is an arithmetic progression
a=800 d=600
From 1985 to 2012 would be the 28th term:
=a+27d
8000 +27(600)=24200

He would receive 24200 in 2012
