Let's say our penguins want to travel around the world, and their preferred method of transportation is by airplane. Planes have a weight limit, and our Antarctic friends need a special type of environment on a plane, so we have to decide how many planes will be needed to transport them comfortably. We'll use the dataset from the theory section.
