At a tourist attraction, each adult ticket cost $32 and each child ticket cost $10. On Saturday, the number of adult tickets sold was 74 less than the number of child tickets. On Sunday, the number of adult tickets sold decreased by 30% while the number of child tickets sold increased by 50%. If a total of 771 tickets were sold on Sunday, how much money was collected on Saturday?

	Adult tickets	Child tickets	Total tickets
Before	1 u	1 u + 74	2 u + 74
Change	- 0.3 u	+ 0.5 u + 37
After	0.7 u	1.5 u + 111	2.2 u + 111

30% x 1 u = ³⁰₁₀₀ x 1 u = 0.3 u 
50% x 1 u = ⁵⁰₁₀₀ x 1 u = 0.5 u
50% x 74 = ⁵⁰₁₀₀ x 74 = 37

Number of tickets sold on Sunday
= 0.7 u + 1.5 u + 111
= 2.2 u + 111

2.2 u + 111 = 771
2.2 u = 771 - 111
2.2 u = 660

1 u = 660 ÷ 2.2 = 300

Amount collected from adult tickets on Saturday
= 1 u x 32
= 300 x 32
= $9600

Amount collected from child tickets on Saturday
= 10(1 u + 74)
= 10(300 + 74)
= 10 x 374
= $3740

Total amount collected on Saturday
= 9600 + 3740
= $13340

Answer(s):$13340
