### Instruction: One ticket to the underground costs $3. In one minute, the metro sells an average of 5 such tickets. What will be the earnings from the tickets in 6 minutes? Please respond by writing a program in Python.### Response: # define the variables
ticket_price = 3  # cost of one ticket
tickets_per_minute = 5  # average number of tickets sold in one minute
time_in_minutes = 6  # time in minutes

# calculate total earnings
total_earnings = ticket_price * tickets_per_minute * time_in_minutes

# print the result
print(total_earnings)
