Given conditions are :
In 1980's, a typical middle-income household earned= $34,757
In 2009, a similar middle-income household earned= $38,550
And we have to find relative increase in income for these households from 1980 to 2009.
So first we will find the total increase in amounts.

Relative increase = 
= 10.91% or rounding it off we get approx 11%.
Hence, the answer is 11%.
12x - 13 - x - 9 + 10x
First, get the like terms together
12x + 10x - x -13 -9
Now, combine like terms
12x + 10x - x = 21x
-13 - 9 = -22
Final Answer:
21x - 22
