At a stadium, each adult ticket cost $34 and each child ticket cost $14. On Thursday, the number of adult tickets sold was 124 less than the number of child tickets. On Friday, the number of adult tickets sold decreased by 35% while the number of child tickets sold increased by 25%. If a total of 1865 tickets were sold on Friday, how much money was collected on Thursday?

	Adult tickets	Child tickets	Total tickets
Before	1 u	1 u + 124	2 u + 124
Change	- 0.35 u	+ 0.25 u + 31
After	0.65 u	1.25 u + 155	1.9 u + 155

35% x 1 u = ³⁵₁₀₀ x 1 u = 0.35 u 
25% x 1 u = ²⁵₁₀₀ x 1 u = 0.25 u
25% x 124 = ²⁵₁₀₀ x 124 = 31

Number of tickets sold on Friday
= 0.65 u + 1.25 u + 155
= 1.9 u + 155

1.9 u + 155 = 1865
1.9 u = 1865 - 155
1.9 u = 1710

1 u = 1710 ÷ 1.9 = 900

Amount collected from adult tickets on Thursday
= 1 u x 34
= 900 x 34
= $30600

Amount collected from child tickets on Thursday
= 14(1 u + 124)
= 14(900 + 124)
= 14 x 1024
= $14336

Total amount collected on Thursday
= 30600 + 14336
= $44936

Answer(s):$44936
