If each ticket cost $17, 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	660 more
Before	2x5	+ 660	10x1
Change	- 1x5	- 330	+ 7x1
After	1x5	+ 330	17x1

	Men		Women
Before	10 u + 660		10 u
Change	- 5 u - 330		+ 7 u
After	5 u + 330		17 u

50% = ⁵⁰₁₀₀ = ¹₂

70% = ⁷⁰₁₀₀ = ⁷₁₀

50% x 660
= ⁵⁰₁₀₀ x 660
= 330

660 - 330 = 330

Total number of tickets sold on Wednesday 
= 5 u + 330 + 17 u
= 22 u + 330 

22 u + 330 = 616
22 u = 616 - 330
22 u = 286

1 u = 286 ÷ 22 = 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 17
= $5967

Answer(s): $5967
