# What´s going on? (insert reference here)

#1

Hello, please help me, i don´t know what´s going on here, this is what my code looks like.

``````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 =  days * 40
if days >= 7:
cost -= 50
elif days >= 3:
cost -= 20
return cost

def trip_cost(city, days, spending_money):
return hotel_cost(days) + plane_ride_cost(city) + rental_car_cost(days) + spending_money
print trip_cost(hotel_cost(5) + plane_ride_cost("Los Angeles") + spending_money(600))``````

Thank you very much!
