here is an example fore you. As you can see I only compare the days once each if line. The reason for this is because if it gets past the low tier if statements we can guarantee that it is greater than x number. So we only have to compare it to the next lowest number.

``````def rental_car_cost(days):
car = 40 * days
if days >= 7:
car -= 50
elif days >= 3:
car -= 20
return car``````

EDIT:

You can also do this one with out variables to hold the data like the following,

``````def rental_car_cost(days):
if days >= 7:
return days * 40 - 50
elif days >= 3:
return days * 40 - 20
return days * 40``````
