Answer:
Amy's yearly salary in 2011 was $27,800
Step-by-step explanation:
we have
[tex]y=25,000+700x[/tex]
where
x ---> is the number of years since 2007
y ---> Amy's yearly salary in dollars
To find out what was her salary in 2011, first determine the value of x
[tex]x=2011-2007=4\ years[/tex]
substitute the value of x in the equation above
[tex]y=25,000+700(4)[/tex]
[tex]y=\$27,800[/tex]
therefore
Amy's yearly salary in 2011 was $27,800
