Program to Determine the Total Revenue from Ticket Sales for an Airline

To calculate the total revenue from ticket sales for an airline, we need to consider the number of passengers and the cost of tickets for each class. Let's assume that the number of passengers and the cost of first-class tickets are provided by the user as input.

Here's a program in Python that calculates the total revenue:

# Get the number of passengers and the cost of first-class tickets from the user
num_passengers = int(input("Enter the number of passengers: "))
ticket_cost_first_class = float(input("Enter the cost of first-class tickets: "))

# Calculate the cost of second-class tickets (20% cheaper than first-class tickets)
ticket_cost_second_class = ticket_cost_first_class * 0.8

# Calculate the total revenue
revenue_first_class = num_passengers * (3/4) * ticket_cost_first_class
revenue_second_class = num_passengers * (1/4) * ticket_cost_second_class
total_revenue = revenue_first_class + revenue_second_class

# Print the total revenue
print("The total revenue from ticket sales is:", total_revenue)

In this program, we first prompt the user to enter the number of passengers and the cost of first-class tickets. We then calculate the cost of second-class tickets, which are 20% cheaper than first-class tickets. Next, we calculate the revenue from first-class tickets by multiplying the number of passengers (three-fourths of the total) by the cost of first-class tickets. Similarly, we calculate the revenue from second-class tickets by multiplying the number of passengers (one-fourth of the total) by the cost of second-class tickets. Finally, we add the revenues from both classes to get the total revenue and print it.

Please note that this program assumes that the number of passengers is a positive integer and the cost of first-class tickets is a positive float. It does not handle any error cases or input validation.
