At a bird park, each adult ticket cost $34 and each child ticket cost $14. On Saturday, the number of adult tickets sold was 170 less than the number of child tickets. On Sunday, the number of adult tickets sold decreased by 45% while the number of child tickets sold increased by 40%. If a total of 1798 tickets were sold on Sunday, how much money was collected on Saturday?

	Adult tickets	Child tickets	Total tickets
Before	1 u	1 u + 170	2 u + 170
Change	- 0.45 u	+ 0.4 u + 68
After	0.55 u	1.4 u + 238	1.95 u + 238

45% x 1 u = ⁴⁵₁₀₀ x 1 u = 0.45 u 
40% x 1 u = ⁴⁰₁₀₀ x 1 u = 0.4 u
40% x 170 = ⁴⁰₁₀₀ x 170 = 68

Number of tickets sold on Sunday
= 0.55 u + 1.4 u + 238
= 1.95 u + 238

1.95 u + 238 = 1798
1.95 u = 1798 - 238
1.95 u = 1560

1 u = 1560 ÷ 1.95 = 800

Amount collected from adult tickets on Saturday
= 1 u x 34
= 800 x 34
= $27200

Amount collected from child tickets on Saturday
= 14(1 u + 170)
= 14(800 + 170)
= 14 x 970
= $13580

Total amount collected on Saturday
= 27200 + 13580
= $40780

Answer(s):$40780
