On Wednesday, 360 more women than men attended a concert. On Thursday, the number of women decreased by 50% and the number of men increased by 80%. 1261 audience attended the concert on Thursday. If each ticket cost $14, how much money was collected from the sale of concert tickets on Wednesday?

	Women		Men
Comparing between the women and the men at first	360 more
Before	2x5	+ 360	5x2
Change	- 1x5	- 180	+ 4x2
After	1x5	+ 180	9x2

	Women		Men
Before	10 u + 360		10 u
Change	- 5 u - 180		+ 8 u
After	5 u + 180		18 u

50% = ⁵⁰₁₀₀ = ¹₂

80% = ⁸⁰₁₀₀ = ⁴₅

50% x 360
= ⁵⁰₁₀₀ x 360
= 180

360 - 180 = 180

Total number of tickets sold on Thursday 
= 5 u + 180 + 18 u
= 23 u + 180 

23 u + 180 = 1261
23 u = 1261 - 180
23 u = 1081

1 u = 1081 ÷ 23 = 47

Total number of tickets sold on Wednesday
= 10 u + 360 + 10 u 
= 20 u + 360
= 20 x 47 + 180
= 1120

Amount collected from the sale of concert tickets on Wednesday
= 1120 x 14
= $15680

Answer(s): $15680
