Help for the spending_money argument


Please i need help, i cant figure out what to do with the spending_money argument, or what to do with it,

def hotel_cost (nights):
return 140 * nights
def plane_ride_cost(city):
if city == "Charlotte":
return 183
elif city == "Tampa":
return 220
elif city == "Pittsburgh":
return 222
elif city == "Los Angeles":
return 475
def rental_car_cost(days):
cost = 40 * days
if days >= 7:
cost -= 50
elif days >= 3:
cost -= 20
return cost
def trip_cost(city,days,spending_money):
return plane_ride_cost(city) + rental_car_cost(days) + hotel_cost(days) + trip_cost(spending_money)


Can you paste your code, so we can see what are we talking about?
While pasting code remember about keeping formating. Paste code, highlight it and use icon </> from the toolbar.


In def trip_cost you have added third argument which is "spending_money", that part is alright, however there is still one mistake in return statement

you are already in trip_cost function, there is no need to refer to it again
