Let T be the total number of seats before the additional number were added

 

And let R be the revenue collected before the additonal seats were added

 

So we have this system

 

.75T(40) + .25T(75)  = R   (1)

 

.75T(40) + (1460 - .75T)(75) = R + 21900  (2)

 

Substituting (1) into (2), we have

 

.75T(40) + (1460 - .75T)(75) = .75T(40) + .25T(75) + 21900   simplify

 

 109500 - 56.25T  = 18.75T + 21900

 

75T =  87600

 

T = 1168

 

And after the seats were added, the number of VIP seats = (1460 -  .75*1168)  =   584

 

And the % of VIP seats after the seats were added = 584/1460  = 40%

 

 

 

cool cool cool
