On Saturday, 700 more women than men attended a concert. On Sunday, the number of women decreased by 10% and the number of men increased by 50%. 750 audience attended the concert on Sunday. If each ticket cost $7, how much money was collected from the sale of concert tickets for the two days?

	Women		Men
Comparing between the women and the men at first	700 more
Before	10x1	+ 700	2x5
Change	- 1x1	- 70	+ 1x5
After	9x1	+ 630	3x5

	Women		Men
Before	10 u + 700		10 u
Change	- 1 u - 70		+ 5 u
After	9 u + 630		15 u

10% = ¹⁰₁₀₀ = ¹₁₀

50% = ⁵⁰₁₀₀ = ¹₂

10% x 700
= ¹⁰₁₀₀ x 700
= 70

700 - 70 = 630

Total number of tickets sold on Sunday 
= 9 u + 630 + 15 u
= 24 u + 630 

24 u + 630 = 750
24 u = 750 - 630
24 u = 120

1 u = 120 ÷ 24 = 5

Total number of tickets sold for the two days
= (10 u + 700) + 10 u + (9 u + 630) + 15 u
= 44 u + 1330
= 44 x 5 + 1330
= 1550

Amount collected from the sale of concert tickets for the two days
= 1550 x 7
= $10850

Answer(s): $10850
