#1

what???
this is my code:
def hotel_cost(nights):
return 140*(nights)
def plane_ride_cost(city):
if city == "Charlotte":
return 183
if city == "Tampa":
return 220
if city == "Pittsburgh":
return 222
if city == "Los Angeles":
return 475
def rental_car_cost(days):
cost = days*40
if days >= 7:
cost - 50
elif days >= 3:
cost - 20
return cost

it says i returned 120 instead of 100

def hotel_cost(nights):

def plane_ride_cost(city):

       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
