You can put this solution on YOUR website!
Let t = number of tickets sold
R+=+65t
C+=+5500+%2B+4t
P+=+65t+-+%285500+%2B+4t%29
P+=+65t+-+5500+-+4t
P+=+61t+-5500
If t+=+850,
P+=+61%2A850+-+5500
P+=+51850+-+5500
P+=+46350
The profit is $46,350 answer
check
C+=+5500+%2B+4t
C+=+5500+%2B+4%2A850
C+=+5500+%2B+3400
C+=+8900
P+=+R+-+C
46350+=+R+-+8900
R+=+46350+%2B+8900
R+=+55250
R+=+65t
65t+=+55250
t+=+850
OK
