Answer:
a)The number of non-digital movie screens reduced by 26916 in four years
b)On average, 6729 non-digital movie screens reduced per year.
Step-by-step explanation:
a)Given that the number of non-digital movie screens was;
2008= 33220
2012=6304
The change is 6304-33220= - 26916
The number of non-digital movie screens reduced by 26916
b) To find the change per year, you know from 2008 to 2012, its 4 years hence divide the change in (a) by 4
= -26916/4 = -6729
On average, 6729 non-digital movie screens reduced per year.
