A flight between Phoenix and San Luis Obispo can hold 120 passengers, and 130 tickets for the flight have been sold (i.e., the flight is overbooked). The fixed cost of the flight (e.g., flying an empty plane between the two cities) is $7,000. The variable cost (e.g., food/fuel) per passenger on the flight is $10. The ticket price is $179. Anyone who shows up and cannot get a seat (because of there are more people than seats) is paid $200 and the passenger can the ticket cost of $179 to a future flight. If a ticket holder does not show up for the flight, the firm allows the passenger to apply the ticket cost to a future flight, but charges a rebooking fee of $50. Suppose that Z denotes the random number of ticket-holders who show up for the flight. Select theleastaccurate statement regarding elements of a model for this setting.

1 The revenue from initial ticket sales is $179 * 130.

2 The number who show up for the flight but cannot get a seat is max(Z- 120, 0)

3 The rebooking revenue from the no-shows is $50 * (130 -Z).

4 The fixed and variable cost of the flight is $7,000 + 120 * $10.
