At a theme park, each adult ticket cost $35 and each child ticket cost $15. On Wednesday, the number of adult tickets sold was 130 less than the number of child tickets. On Thursday, the number of adult tickets sold decreased by 20% while the number of child tickets sold increased by 10%. If a total of 333 tickets were sold on Thursday, how much money was collected on Wednesday?

	Adult tickets	Child tickets	Total tickets
Before	1 u	1 u + 130	2 u + 130
Change	- 0.2 u	+ 0.1 u + 13
After	0.8 u	1.1 u + 143	1.9 u + 143

20% x 1 u = ²⁰₁₀₀ x 1 u = 0.2 u 
10% x 1 u = ¹⁰₁₀₀ x 1 u = 0.1 u
10% x 130 = ¹⁰₁₀₀ x 130 = 13

Number of tickets sold on Thursday
= 0.8 u + 1.1 u + 143
= 1.9 u + 143

1.9 u + 143 = 333
1.9 u = 333 - 143
1.9 u = 190

1 u = 190 ÷ 1.9 = 100

Amount collected from adult tickets on Wednesday
= 1 u x 35
= 100 x 35
= $3500

Amount collected from child tickets on Wednesday
= 15(1 u + 130)
= 15(100 + 130)
= 15 x 230
= $3450

Total amount collected on Wednesday
= 3500 + 3450
= $6950

Answer(s):$6950
