At a stadium, each adult ticket cost $21 and each child ticket cost $9. On Tuesday, the number of adult tickets sold was 95 less than the number of child tickets. On Wednesday, the number of adult tickets sold decreased by 35% while the number of child tickets sold increased by 40%. If a total of 953 tickets were sold on Wednesday, how much money was collected on Tuesday?

	Adult tickets	Child tickets	Total tickets
Before	1 u	1 u + 95	2 u + 95
Change	- 0.35 u	+ 0.4 u + 38
After	0.65 u	1.4 u + 133	2.05 u + 133

35% x 1 u = ³⁵₁₀₀ x 1 u = 0.35 u 
40% x 1 u = ⁴⁰₁₀₀ x 1 u = 0.4 u
40% x 95 = ⁴⁰₁₀₀ x 95 = 38

Number of tickets sold on Wednesday
= 0.65 u + 1.4 u + 133
= 2.05 u + 133

2.05 u + 133 = 953
2.05 u = 953 - 133
2.05 u = 820

1 u = 820 ÷ 2.05 = 400

Amount collected from adult tickets on Tuesday
= 1 u x 21
= 400 x 21
= $8400

Amount collected from child tickets on Tuesday
= 9(1 u + 95)
= 9(400 + 95)
= 9 x 495
= $4455

Total amount collected on Tuesday
= 8400 + 4455
= $12855

Answer(s):$12855
