On Saturday, 710 more men than women attended a concert. On Sunday, the number of men decreased by 50% and the number of women increased by 70%. 531 audience attended the concert on Sunday. If each ticket cost $8, 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	710 more
Before	2x5	+ 710	10x1
Change	- 1x5	- 355	+ 7x1
After	1x5	+ 355	17x1

	Men		Women
Before	10 u + 710		10 u
Change	- 5 u - 355		+ 7 u
After	5 u + 355		17 u

50% = ⁵⁰₁₀₀ = ¹₂

70% = ⁷⁰₁₀₀ = ⁷₁₀

50% x 710
= ⁵⁰₁₀₀ x 710
= 355

710 - 355 = 355

Total number of tickets sold on Sunday 
= 5 u + 355 + 17 u
= 22 u + 355 

22 u + 355 = 531
22 u = 531 - 355
22 u = 176

1 u = 176 ÷ 22 = 8

Total number of tickets sold to all the women
= 10 u + 17 u
= 27 u 
= 27 x 8
= 216

Amount collected from the sale of concert tickets to all the women
= 216 x 8
= $1728

Answer(s): $1728
