At a museum, each adult ticket cost $33 and each child ticket cost $17. On Wednesday, the number of adult tickets sold was 190 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 30%. If a total of 1752 tickets were sold on Thursday, how much money was collected on Wednesday?

	Adult tickets	Child tickets	Total tickets
Before	1 u	1 u + 190	2 u + 190
Change	- 0.15 u	+ 0.3 u + 57
After	0.85 u	1.3 u + 247	2.15 u + 247

15% x 1 u = ¹⁵₁₀₀ x 1 u = 0.15 u 
30% x 1 u = ³⁰₁₀₀ x 1 u = 0.3 u
30% x 190 = ³⁰₁₀₀ x 190 = 57

Number of tickets sold on Thursday
= 0.85 u + 1.3 u + 247
= 2.15 u + 247

2.15 u + 247 = 1752
2.15 u = 1752 - 247
2.15 u = 1505

1 u = 1505 ÷ 2.15 = 700

Amount collected from adult tickets on Wednesday
= 1 u x 33
= 700 x 33
= $23100

Amount collected from child tickets on Wednesday
= 17(1 u + 190)
= 17(700 + 190)
= 17 x 890
= $15130

Total amount collected on Wednesday
= 23100 + 15130
= $38230

Answer(s):$38230
