On Monday, 120 more women than men attended a concert. On Tuesday, the number of women decreased by 10% and the number of men increased by 60%. 1158 audience attended the concert on Tuesday. If each ticket cost $13, 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	120 more
Before	10x1	+ 120	5x2
Change	- 1x1	- 12	+ 3x2
After	9x1	+ 108	8x2

	Women		Men
Before	10 u + 120		10 u
Change	- 1 u - 12		+ 6 u
After	9 u + 108		16 u

10% = ¹⁰₁₀₀ = ¹₁₀

60% = ⁶⁰₁₀₀ = ³₅

10% x 120
= ¹⁰₁₀₀ x 120
= 12

120 - 12 = 108

Total number of tickets sold on Tuesday 
= 9 u + 108 + 16 u
= 25 u + 108 

25 u + 108 = 1158
25 u = 1158 - 108
25 u = 1050

1 u = 1050 ÷ 25 = 42

Total number of tickets sold for the two days
= (10 u + 120) + 10 u + (9 u + 108) + 16 u
= 45 u + 228
= 45 x 42 + 228
= 2118

Amount collected from the sale of concert tickets for the two days
= 2118 x 13
= $27534

Answer(s): $27534
