Renee just began her job as an elementary school teacher. she is told that her starting salary will be $35000 per year. she is also told that her salary will increase to $36960 in 7 years. assume that x = the years worked and y = salary in dollars. what is the rate of change of renee's salary?

Renee's salary begins at $35000 and ends 7 years later as $36960. The salary increase is $1960.

Over 7 years, then, the rate of change of Renee's salary is

$1960

= $280/year.

7 yrs
