Question

NEED DONE ASAP. IT'S 12AM AND I WANNA GET THIS DONE SO I CAN SLEEP..

Answer 1

The options seem a bit mis-formatted but here is the way p is computed:

the decrease is 2000-1600

and it is relative to: 2000  (2003 attendance)

so $p=100 \frac{2000-1600}{2000} = 100 \frac{400}{2000}$

and so that aligns with your Option A. Options B, C, D look incorrect for sure.
