At a museum, each adult ticket cost $29 and each child ticket cost $5. On Tuesday, the number of adult tickets sold was 60 less than the number of child tickets. On Wednesday, the number of adult tickets sold decreased by 15% while the number of child tickets sold increased by 35%. If a total of 961 tickets were sold on Wednesday, how much money was collected on Tuesday?

	Adult tickets	Child tickets	Total tickets
Before	1 u	1 u + 60	2 u + 60
Change	- 0.15 u	+ 0.35 u + 21
After	0.85 u	1.35 u + 81	2.2 u + 81

15% x 1 u = ¹⁵₁₀₀ x 1 u = 0.15 u 
35% x 1 u = ³⁵₁₀₀ x 1 u = 0.35 u
35% x 60 = ³⁵₁₀₀ x 60 = 21

Number of tickets sold on Wednesday
= 0.85 u + 1.35 u + 81
= 2.2 u + 81

2.2 u + 81 = 961
2.2 u = 961 - 81
2.2 u = 880

1 u = 880 ÷ 2.2 = 400

Amount collected from adult tickets on Tuesday
= 1 u x 29
= 400 x 29
= $11600

Amount collected from child tickets on Tuesday
= 5(1 u + 60)
= 5(400 + 60)
= 5 x 460
= $2300

Total amount collected on Tuesday
= 11600 + 2300
= $13900

Answer(s):$13900
