Guys im stuck a little help?

-Oops, try again. trip_cost('Tampa', 5) raised an error: global name 'hotel_costs' is not defined
-Oops, try again. trip_cost('Pittsburgh', 5) raised an error: global name 'hotel_costs' is not defined
-Oops, try again. trip_cost('Tampa', 8) raised an error: global name 'hotel_costs' is not defined
-Oops, try again. trip_cost('Los Angeles', 5) raised an error: global name 'hotel_costs' is not defined

``````Replace this line with your code.
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):
rental = 40 * days
if days >= 7:
return rental - 50
elif days >= 3 and days < 7:
return rental - 20
else:
return rental

def trip_cost(city, days):
a = hotel_costs(days)
b = plane_ride_cost(city)
c = rental_car_cost(days)
return a + b + c``````

try returning
this
return rental_car_cost(days) + hotel_cost(days) + plane_ride_cost(city)

rather than creating seperate variables (as they already exist further up in the code).
other than that remove the (s) from hotel_costs and call the function again, it will relate back to the previous variable with the new argument (days)

#3

@darkbrightstarshot, hotel_cost and hotel_costs are two different things

#5

according to the instructions on the page:
"It is completely valid to call the hotel_cost(nights) function with the variable days"
they are the same variable using different argument?
please correct me if im wrong?

#6

you are right, but that is not the point i wanted to make, your function is named hotel_cost, but when you call the function you use hotel_costS. That doesnt' work

#7

aaah i see whats happened, you replied to my reply rather than the OP, i misinterpreted your comment as shooting down my answer apologies

#8

no, this is not your fault, i mixed it up. Sorry, i will fix it
