Answer 1

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.

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.
