	Women		Men
Comparing between the women and the men at first	370 more
Before	10x1	+ 370	5x2
Change	- 1x1	- 37	+ 4x2
After	9x1	+ 333	9x2

	Women		Men
Before	10 u + 370		10 u
Change	- 1 u - 37		+ 8 u
After	9 u + 333		18 u

10% = ¹⁰₁₀₀ = ¹₁₀

80% = ⁸⁰₁₀₀ = ⁴₅

10% x 370
= ¹⁰₁₀₀ x 370
= 37

370 - 37 = 333

Total number of tickets sold on Thursday 
= 9 u + 333 + 18 u
= 27 u + 333 

27 u + 333 = 630
27 u = 630 - 333
27 u = 297

1 u = 297 ÷ 27 = 11

Total number of tickets sold on Wednesday
= 10 u + 370 + 10 u 
= 20 u + 370
= 20 x 11 + 333
= 553

Amount collected from the sale of concert tickets on Wednesday
= 553 x 5
= $2765

Answer(s): $2765
