Answer:
10.42
Step-by-step explanation:
Change between 2004 and 2011 can be used to calculate linear change per year: 15.37 - 11.52 = 3.85 / 7 = 0.55 <== Change per year
Using 0.55 per year, we can find the answer by subtracting 0.55 from 11.52 2 times to get our final answer. 11.52 - 0.55(2) = 10.42 in 2013.
Good luck ^^
