Answer
(a) The average starting salary for 2006 graduates earning MBAs is 95,400 dollars.
(b) $s(2009)=104,000$
Work Step by Step
(a) In this case $t=2006$ and $s(t)=95,400$ therefore a sentence of interpretation is:
The average starting salary for 2006 graduates earning MBAs is 95,400 dollars.
(b) Here, the year of graduation is 2009 and their average salary is 104,000 dollars. If we want to translate it to the function, $t$ represents the year of graduation, therefore $t=2009$
$s(t)$ represents the average starting salary, therefore $s(t)=104,000$.
$s(2009)=104,000$
