You can put this solution on YOUR website! 2,500x+5,000(770-x)=2,800,000
2,500x+3,850,000-5,000x=2,800,000
-2,500x=2,800,000-3,850,000
-2,500x=-1,050,000
x=-1,050,000/-2,500
x=420 semi-VIP tickets sold.
770-420=350 VIP tickets sold.
Proof:
2,500*420+5,000*350=2,800,000
1,050,000+1,750,000=2,800,000
2,800,000=2,800,000
