You can  put this solution on YOUR website! 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
