On Saturday, 470 more women than men attended a concert. On Sunday, the number of women decreased by 40% and the number of men increased by 70%. 811 audience attended the concert on Sunday. If each ticket cost $14, 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	470 more
Before	5x2	+ 470	10x1
Change	- 2x2	- 188	+ 7x1
After	3x2	+ 282	17x1

	Women		Men
Before	10 u + 470		10 u
Change	- 4 u - 188		+ 7 u
After	6 u + 282		17 u

40% = ⁴⁰₁₀₀ = ²₅

70% = ⁷⁰₁₀₀ = ⁷₁₀

40% x 470
= ⁴⁰₁₀₀ x 470
= 188

470 - 188 = 282

Total number of tickets sold on Sunday 
= 6 u + 282 + 17 u
= 23 u + 282 

23 u + 282 = 811
23 u = 811 - 282
23 u = 529

1 u = 529 ÷ 23 = 23

Total number of tickets sold for the two days
= (10 u + 470) + 10 u + (6 u + 282) + 17 u
= 43 u + 752
= 43 x 23 + 752
= 1741

Amount collected from the sale of concert tickets for the two days
= 1741 x 14
= $24374

Answer(s): $24374
