Answer:
# Ask user for the number of tickets
num_tickets = input("How many tickets would you like to purchase? ")
# Convert the user input to an integer
num_tickets = int(num_tickets)
# Set the price per ticket
PRICE_PER_TICKET = 10
# Calculate the total cost
total_cost = num_tickets * PRICE_PER_TICKET
# Print the number of tickets and total cost to the user
print("You want to purchase " + str(num_tickets) + " tickets, and the total cost is $" + str(total_cost) + ".")
