On Wednesday, 480 more women than men attended a concert. On Thursday, the number of women decreased by 40% and the number of men increased by 70%. 1024 audience attended the concert on Thursday. If each ticket cost $18, 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	480 more
Before	5x2	+ 480	10x1
Change	- 2x2	- 192	+ 7x1
After	3x2	+ 288	17x1

	Women		Men
Before	10 u + 480		10 u
Change	- 4 u - 192		+ 7 u
After	6 u + 288		17 u

40% = ⁴⁰₁₀₀ = ²₅

70% = ⁷⁰₁₀₀ = ⁷₁₀

40% x 480
= ⁴⁰₁₀₀ x 480
= 192

480 - 192 = 288

Total number of tickets sold on Thursday 
= 6 u + 288 + 17 u
= 23 u + 288 

23 u + 288 = 1024
23 u = 1024 - 288
23 u = 736

1 u = 736 ÷ 23 = 32

Total number of tickets sold for the two days
= (10 u + 480) + 10 u + (6 u + 288) + 17 u
= 43 u + 768
= 43 x 32 + 768
= 2144

Amount collected from the sale of concert tickets for the two days
= 2144 x 18
= $38592

Answer(s): $38592
