	Men		Women
Comparing between the men and the women at first	510 more
Before	2x5	+ 510	10x1
Change	- 1x5	- 255	+ 7x1
After	1x5	+ 255	17x1

	Men		Women
Before	10 u + 510		10 u
Change	- 5 u - 255		+ 7 u
After	5 u + 255		17 u

50% = ⁵⁰₁₀₀ = ¹₂

70% = ⁷⁰₁₀₀ = ⁷₁₀

50% x 510
= ⁵⁰₁₀₀ x 510
= 255

510 - 255 = 255

Total number of tickets sold on Tuesday 
= 5 u + 255 + 17 u
= 22 u + 255 

22 u + 255 = 607
22 u = 607 - 255
22 u = 352

1 u = 352 ÷ 22 = 16

Total number of tickets sold to all the women
= 10 u + 17 u
= 27 u 
= 27 x 16
= 432

Amount collected from the sale of concert tickets to all the women
= 432 x 9
= $3888

Answer(s): $3888
