At a safari park, each adult ticket cost $38 and each child ticket cost $16. On Wednesday, the number of adult tickets sold was 165 less than the number of child tickets. On Thursday, the number of adult tickets sold decreased by 5% while the number of child tickets sold increased by 40%. If a total of 1876 tickets were sold on Thursday, how much money was collected on Wednesday?

	Adult tickets	Child tickets	Total tickets
Before	1 u	1 u + 165	2 u + 165
Change	- 0.05 u	+ 0.4 u + 66
After	0.95 u	1.4 u + 231	2.35 u + 231

5% x 1 u = ⁵₁₀₀ x 1 u = 0.05 u 
40% x 1 u = ⁴⁰₁₀₀ x 1 u = 0.4 u
40% x 165 = ⁴⁰₁₀₀ x 165 = 66

Number of tickets sold on Thursday
= 0.95 u + 1.4 u + 231
= 2.35 u + 231

2.35 u + 231 = 1876
2.35 u = 1876 - 231
2.35 u = 1645

1 u = 1645 ÷ 2.35 = 700

Amount collected from adult tickets on Wednesday
= 1 u x 38
= 700 x 38
= $26600

Amount collected from child tickets on Wednesday
= 16(1 u + 165)
= 16(700 + 165)
= 16 x 865
= $13840

Total amount collected on Wednesday
= 26600 + 13840
= $40440

Answer(s):$40440
