Im stuck at car rental cost for the vacation.
The error message is "Oops, try again. It looks like rental_car_cost returns None instead of the correct amount (40) for 1 days. "
How do i fix this?
def rental_car_cost(days): totalcost= 40*days if days >= 7: return totalcost-50 elif days >= 3 and days<7: return totalcost-20
