	Women		Men
Comparing between the women and the men at first	560 more
Before	5x2	+ 560	10x1
Change	- 1x2	- 112	+ 7x1
After	4x2	+ 448	17x1

	Women		Men
Before	10 u + 560		10 u
Change	- 2 u - 112		+ 7 u
After	8 u + 448		17 u

20% = ²⁰₁₀₀ = ¹₅

70% = ⁷⁰₁₀₀ = ⁷₁₀

20% x 560
= ²⁰₁₀₀ x 560
= 112

560 - 112 = 448

Total number of tickets sold on Wednesday 
= 8 u + 448 + 17 u
= 25 u + 448 

25 u + 448 = 1398
25 u = 1398 - 448
25 u = 950

1 u = 950 ÷ 25 = 38

Total number of tickets sold to all the men
= 10 u + 17 u
= 27 u 
= 27 x 38
= 1026

Amount collected from the sale of concert tickets to all the men
= 1026 x 7
= $7182

Answer(s): $7182
