Answer:
The required equation is:

Explanation:
Consider the provided information.
Let x represents tickets sold.
A theme park charges a flat fee of $500 for group bookings of more than 25 tickets, plus $20 per ticket for up to 100 tickets and $17 per ticket thereafter.
The charges for booking 100 tickets will be:

If you by more than 100 tickets theme park charges $17,
Thus, charges for x tickets will be =

The limit equation represents the average cost per ticket as the number of tickets purchased becomes very high.
The Cost of one ticket of the theme park =

Now solve the above limit equation that will gives you the average cost per ticket as the number of tickets purchased becomes very high.


Hence, the cost per ticket is $17 as the number of tickets purchased becomes very high.
