Oops, try again. It looks like rental_car_cost returns None instead of the correct amount (40) for 1 days.
def rental_car_cost(days): daily = 40 * days if days >= 7: daily /= 50 elif days >= 3: daily /= 20 return daily
OK so, idk wtf to do, honestly im completely lost. What should be the sign for deduction? How do i represent that everyday $40 is added.. i feel so dumb
