	Women		Men
Comparing between the women and the men at first	580 more
Before	2x5	+ 580	10x1
Change	- 1x5	- 290	+ 7x1
After	1x5	+ 290	17x1

	Women		Men
Before	10 u + 580		10 u
Change	- 5 u - 290		+ 7 u
After	5 u + 290		17 u

50% = ⁵⁰₁₀₀ = ¹₂

70% = ⁷⁰₁₀₀ = ⁷₁₀

50% x 580
= ⁵⁰₁₀₀ x 580
= 290

580 - 290 = 290

Total number of tickets sold on Tuesday 
= 5 u + 290 + 17 u
= 22 u + 290 

22 u + 290 = 576
22 u = 576 - 290
22 u = 286

1 u = 286 ÷ 22 = 13

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

Amount collected from the sale of concert tickets to all the men
= 351 x 13
= $4563

Answer(s): $4563
