What is the answer for the additional question?
Official Explanation
Based upon the linear model, a salary comparable to that paid to Alex Rodriguez in 2001 would be expected in approximately ____________.
(A) 2002
(B) 2005
(C) 2009
(D) 2011
(E) 2020
Explanation
Use the slope of the dotted line to estimate when it will reach the $22 million territory of Rodriguez’s salary. That will require an increase in salary of about $7 million beyond the last visible point on the line (2002). Based on the slope, it will take approximately 9 years to increase another $7 million, so it will get there around 2011.
