On Friday, 700 more men than women attended a concert. On Saturday, the number of men decreased by 20% and the number of women increased by 70%. 885 audience attended the concert on Saturday. If each ticket cost $5, 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	700 more
Before	5x2	+ 700	10x1
Change	- 1x2	- 140	+ 7x1
After	4x2	+ 560	17x1

	Men		Women
Before	10 u + 700		10 u
Change	- 2 u - 140		+ 7 u
After	8 u + 560		17 u

20% = ²⁰₁₀₀ = ¹₅

70% = ⁷⁰₁₀₀ = ⁷₁₀

20% x 700
= ²⁰₁₀₀ x 700
= 140

700 - 140 = 560

Total number of tickets sold on Saturday 
= 8 u + 560 + 17 u
= 25 u + 560 

25 u + 560 = 885
25 u = 885 - 560
25 u = 325

1 u = 325 ÷ 25 = 13

Total number of tickets sold to all the women
= 10 u + 17 u
= 27 u 
= 27 x 13
= 351

Amount collected from the sale of concert tickets to all the women
= 351 x 5
= $1755

Answer(s): $1755
