More Help 1:

Let the attendance for Thursday be represented as $x$ , how can you represent the other days' attendances?

More Help 2:

Daily Attendances:
Thursday $= x$
Friday $= x + 5500$
Saturday $= 2x$
Sunday $= 2x + 3000$
$x + (x + 5500) + 2x + (2x + 3000) = 36700$

Partial Answer:

Thursday's attendance $(x) = 4700$ people
How many people attended on the other days?
