At a tourist attraction, each adult ticket cost $30 and each child ticket cost $16. On Wednesday, the number of adult tickets sold was 160 less than the number of child tickets. On Thursday, the number of adult tickets sold decreased by 30% while the number of child tickets sold increased by 15%. If a total of 1664 tickets were sold on Thursday, how much money was collected on Wednesday?

	Adult tickets	Child tickets	Total tickets
Before	1 u	1 u + 160	2 u + 160
Change	- 0.3 u	+ 0.15 u + 24
After	0.7 u	1.15 u + 184	1.85 u + 184

30% x 1 u = ³⁰₁₀₀ x 1 u = 0.3 u 
15% x 1 u = ¹⁵₁₀₀ x 1 u = 0.15 u
15% x 160 = ¹⁵₁₀₀ x 160 = 24

Number of tickets sold on Thursday
= 0.7 u + 1.15 u + 184
= 1.85 u + 184

1.85 u + 184 = 1664
1.85 u = 1664 - 184
1.85 u = 1480

1 u = 1480 ÷ 1.85 = 800

Amount collected from adult tickets on Wednesday
= 1 u x 30
= 800 x 30
= $24000

Amount collected from child tickets on Wednesday
= 16(1 u + 160)
= 16(800 + 160)
= 16 x 960
= $15360

Total amount collected on Wednesday
= 24000 + 15360
= $39360

Answer(s):$39360
