At a tourist attraction, each adult ticket cost $37 and each child ticket cost $18. On Tuesday, the number of adult tickets sold was 125 less than the number of child tickets. On Wednesday, the number of adult tickets sold decreased by 5% while the number of child tickets sold increased by 40%. If a total of 880 tickets were sold on Wednesday, how much money was collected on Tuesday?

	Adult tickets	Child tickets	Total tickets
Before	1 u	1 u + 125	2 u + 125
Change	- 0.05 u	+ 0.4 u + 50
After	0.95 u	1.4 u + 175	2.35 u + 175

5% x 1 u = ⁵₁₀₀ x 1 u = 0.05 u 
40% x 1 u = ⁴⁰₁₀₀ x 1 u = 0.4 u
40% x 125 = ⁴⁰₁₀₀ x 125 = 50

Number of tickets sold on Wednesday
= 0.95 u + 1.4 u + 175
= 2.35 u + 175

2.35 u + 175 = 880
2.35 u = 880 - 175
2.35 u = 705

1 u = 705 ÷ 2.35 = 300

Amount collected from adult tickets on Tuesday
= 1 u x 37
= 300 x 37
= $11100

Amount collected from child tickets on Tuesday
= 18(1 u + 125)
= 18(300 + 125)
= 18 x 425
= $7650

Total amount collected on Tuesday
= 11100 + 7650
= $18750

Answer(s):$18750
