At a bird park, each adult ticket cost $25 and each child ticket cost $17. On Wednesday, the number of adult tickets sold was 112 less than the number of child tickets. On Thursday, the number of adult tickets sold decreased by 15% while the number of child tickets sold increased by 25%. If a total of 560 tickets were sold on Thursday, how much money was collected on Wednesday?

	Adult tickets	Child tickets	Total tickets
Before	1 u	1 u + 112	2 u + 112
Change	- 0.15 u	+ 0.25 u + 28
After	0.85 u	1.25 u + 140	2.1 u + 140

15% x 1 u = ¹⁵₁₀₀ x 1 u = 0.15 u 
25% x 1 u = ²⁵₁₀₀ x 1 u = 0.25 u
25% x 112 = ²⁵₁₀₀ x 112 = 28

Number of tickets sold on Thursday
= 0.85 u + 1.25 u + 140
= 2.1 u + 140

2.1 u + 140 = 560
2.1 u = 560 - 140
2.1 u = 420

1 u = 420 ÷ 2.1 = 200

Amount collected from adult tickets on Wednesday
= 1 u x 25
= 200 x 25
= $5000

Amount collected from child tickets on Wednesday
= 17(1 u + 112)
= 17(200 + 112)
= 17 x 312
= $5304

Total amount collected on Wednesday
= 5000 + 5304
= $10304

Answer(s):$10304
