marissa [1.9K]

Answer:

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

Step-by-step explanation:

we have

$y=25,000+700x$

where

x ---> is the number of years since 2007

y ---> Amy's yearly salary in dollars

$x=2011-2007=4\ years$

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
