It's printing, but keeps erroring saying: "Oops, try again.

trip_cost should take exactly three parameters: city, days, and spending_money (in that order).", but they're in that order and I can't figure this out. Please assist.

```
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
return cost
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) + spending_money
print trip_cost("Los Angeles", 5, 600)
```
