On Tuesday, 360 more men than women attended a concert. On Wednesday, the number of men decreased by 50% and the number of women increased by 80%. 801 audience attended the concert on Wednesday. If each ticket cost $20, how much money was collected from the sale of concert tickets on Tuesday?

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

	Men		Women
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 Wednesday 
= 5 u + 180 + 18 u
= 23 u + 180 

23 u + 180 = 801
23 u = 801 - 180
23 u = 621

1 u = 621 ÷ 23 = 27

Total number of tickets sold on Tuesday
= 10 u + 360 + 10 u 
= 20 u + 360
= 20 x 27 + 180
= 720

Amount collected from the sale of concert tickets on Tuesday
= 720 x 20
= $14400

Answer(s): $14400
