On Wednesday, 300 more men than women attended a concert. On Thursday, the number of men decreased by 20% and the number of women increased by 70%. 890 audience attended the concert on Thursday. If each ticket cost $16, how much money was collected from the sale of concert tickets to all the women?

	Men		Women
Comparing between the men and the women at first	300 more
Before	5x2	+ 300	10x1
Change	- 1x2	- 60	+ 7x1
After	4x2	+ 240	17x1

	Men		Women
Before	10 u + 300		10 u
Change	- 2 u - 60		+ 7 u
After	8 u + 240		17 u

20% = ²⁰₁₀₀ = ¹₅

70% = ⁷⁰₁₀₀ = ⁷₁₀

20% x 300
= ²⁰₁₀₀ x 300
= 60

300 - 60 = 240

Total number of tickets sold on Thursday 
= 8 u + 240 + 17 u
= 25 u + 240 

25 u + 240 = 890
25 u = 890 - 240
25 u = 650

1 u = 650 ÷ 25 = 26

Total number of tickets sold to all the women
= 10 u + 17 u
= 27 u 
= 27 x 26
= 702

Amount collected from the sale of concert tickets to all the women
= 702 x 16
= $11232

Answer(s): $11232
