Answer 1

Answer:

Step-by-step explanation:

Average salary is given 553.7x + 27,966

where x is related as 1985 + x in years

So simply for year 1991

1991 = 1985 + 6

x = 6

We will feed the value in equation

553.7x + 27,966

=553.7 * 6 + 27966

=31288.2

Average salary (rounded off) = 31,288 $

Hope it helps :-)
