Oops, try again. hotel_cost(1) returned 40 instead of the correct value 140

```
def rental_car_cost(days):
return 140*days
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 hotel_cost(days):
cost = 40 * days
if days >= 7:
cost -= 50
elif days >= 3:
cost -= 20
return cost
def trip_cost(days, city):
return rental_car_cost(days) + hotel_cost(days) + plane_ride_cost(city)
```
