On Saturday, 750 more women than men attended a concert. On Sunday, the number of women decreased by 50% and the number of men increased by 70%. 1343 audience attended the concert on Sunday. If each ticket cost $10, how much money was collected from the sale of concert tickets to all the men?

	Women		Men
Comparing between the women and the men at first	750 more
Before	2x5	+ 750	10x1
Change	- 1x5	- 375	+ 7x1
After	1x5	+ 375	17x1

	Women		Men
Before	10 u + 750		10 u
Change	- 5 u - 375		+ 7 u
After	5 u + 375		17 u

50% = ⁵⁰₁₀₀ = ¹₂

70% = ⁷⁰₁₀₀ = ⁷₁₀

50% x 750
= ⁵⁰₁₀₀ x 750
= 375

750 - 375 = 375

Total number of tickets sold on Sunday 
= 5 u + 375 + 17 u
= 22 u + 375 

22 u + 375 = 1343
22 u = 1343 - 375
22 u = 968

1 u = 968 ÷ 22 = 44

Total number of tickets sold to all the men
= 10 u + 17 u
= 27 u 
= 27 x 44
= 1188

Amount collected from the sale of concert tickets to all the men
= 1188 x 10
= $11880

Answer(s): $11880
