# A group of friends rent a house at the beach for spring break. If nine of them share the house, it costs $150 each. Is the cost to each person directly or inversely proportional to the number of people sharing the house?

Inversely: as the number of people increases the individual cost decreases.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
