If n is number of increments of 50 dollars, then price becomes 650-50n.
If use x for counting each increment of $50 then x=50n; and number of tickets is 50+10n.

PRICE       TICKETS
650-x       50+x/5

Revenue is .
Maximum revenue is exactly in the middle of the two zeros of y.

Zeros are 650 and -250.
Exact Middle of the two zeros: 200 dollars decrease from $650. Price there for max revenue, $450, best ticket price.
Max Revenue: $40500.
