Answer:

Amy's yearly salary in 2011 was $27,800

Step-by-step explanation:

we have

$y=25,000+700x$

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

$x=2011-2007=4\ years$

substitute the value of x in the equation above

$y=25,000+700(4)$

$y=\$27,800$

therefore

Amy's yearly salary in 2011 was $27,800
