The expression
Average age = 553.7x + 27,966
can be used to approximate the average annual salary in dollars of public school teachers in the year 1985 + x.

What was the average teacher's salary in 1991?
If 1985+x = 1991, x = 6
----------------------------
Average age in 1991 is 553.7*6 + 27,966 = 31288.20
-------------------------------------------------------
Round your answer to the nearest whole number.
Average teacher salary in 1991 was $31,288
