At a concert hall, each adult ticket cost $32 and each child ticket cost $14. On Saturday, the number of adult tickets sold was 96 less than the number of child tickets. On Sunday, the number of adult tickets sold decreased by 20% while the number of child tickets sold increased by 25%. If a total of 530 tickets were sold on Sunday, how much money was collected on Saturday?

	Adult tickets	Child tickets	Total tickets
Before	1 u	1 u + 96	2 u + 96
Change	- 0.2 u	+ 0.25 u + 24
After	0.8 u	1.25 u + 120	2.05 u + 120

20% x 1 u = ²⁰₁₀₀ x 1 u = 0.2 u 
25% x 1 u = ²⁵₁₀₀ x 1 u = 0.25 u
25% x 96 = ²⁵₁₀₀ x 96 = 24

Number of tickets sold on Sunday
= 0.8 u + 1.25 u + 120
= 2.05 u + 120

2.05 u + 120 = 530
2.05 u = 530 - 120
2.05 u = 410

1 u = 410 ÷ 2.05 = 200

Amount collected from adult tickets on Saturday
= 1 u x 32
= 200 x 32
= $6400

Amount collected from child tickets on Saturday
= 14(1 u + 96)
= 14(200 + 96)
= 14 x 296
= $4144

Total amount collected on Saturday
= 6400 + 4144
= $10544

Answer(s):$10544
