Answer
The average income of an American woman with a bachelor’s degree in 2008 is $\$51,579.2$.
Work Step by Step
The year 2008 is 3 years after 2005.
Thus, $x=12008−2005=3$.
To find the average income of an American woman with a
bachelor’s degree in 2008, substitute 3 to x in the given equation to have:
$\\\\y=4207.4(3)+38,957
\\\\y=12622.2+38957
\\\\y=51579.2$
