On Thursday, 110 more women than men attended a concert. On Friday, the number of women decreased by 40% and the number of men increased by 50%. 717 audience attended the concert on Friday. If each ticket cost $19, 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	110 more
Before	5x2	+ 110	2x5
Change	- 2x2	- 44	+ 1x5
After	3x2	+ 66	3x5

	Women		Men
Before	10 u + 110		10 u
Change	- 4 u - 44		+ 5 u
After	6 u + 66		15 u

40% = ⁴⁰₁₀₀ = ²₅

50% = ⁵⁰₁₀₀ = ¹₂

40% x 110
= ⁴⁰₁₀₀ x 110
= 44

110 - 44 = 66

Total number of tickets sold on Friday 
= 6 u + 66 + 15 u
= 21 u + 66 

21 u + 66 = 717
21 u = 717 - 66
21 u = 651

1 u = 651 ÷ 21 = 31

Total number of tickets sold for the two days
= (10 u + 110) + 10 u + (6 u + 66) + 15 u
= 41 u + 176
= 41 x 31 + 176
= 1447

Amount collected from the sale of concert tickets for the two days
= 1447 x 19
= $27493

Answer(s): $27493
