Take A vacation/ Plan you trip!



Traceback (most recent call last):

TypeError: unsupported operand type(s) for +: 'int' and 'NoneType'

I am not sure why I am getting this error. Thank you so much for the help.

    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 rental_car_cost(days) + hotel_cost(days) + plane_ride_cost(city) + spending_money
trip_cost ("los Angeles",5,600)


Have here

trip_cost ("los Angeles",5,600)

Inside your call function you wrote

los Angeles

Instead of

Los Angeles


Thank you so much! I was so confused on why it was not working.
