On Thursday, 380 more women than men attended a concert. On Friday, the number of women decreased by 40% and the number of men increased by 50%. 984 audience attended the concert on Friday. If each ticket cost $6, how much money was collected from the sale of concert tickets for the two days?

	Women		Men
Comparing between the women and the men at first	380 more
Before	5x2	+ 380	2x5
Change	- 2x2	- 152	+ 1x5
After	3x2	+ 228	3x5

	Women		Men
Before	10 u + 380		10 u
Change	- 4 u - 152		+ 5 u
After	6 u + 228		15 u

40% = ⁴⁰₁₀₀ = ²₅

50% = ⁵⁰₁₀₀ = ¹₂

40% x 380
= ⁴⁰₁₀₀ x 380
= 152

380 - 152 = 228

Total number of tickets sold on Friday 
= 6 u + 228 + 15 u
= 21 u + 228 

21 u + 228 = 984
21 u = 984 - 228
21 u = 756

1 u = 756 ÷ 21 = 36

Total number of tickets sold for the two days
= (10 u + 380) + 10 u + (6 u + 228) + 15 u
= 41 u + 608
= 41 x 36 + 608
= 2084

Amount collected from the sale of concert tickets for the two days
= 2084 x 6
= $12504

Answer(s): $12504
