Hannah, Jim, and Julie are on a hiking trip with 2 children and their two dogs. They come to a huge lake with an island int he middle. Nearby is a small sailboat. The sailboat can hold 1 adult, or 2 kids, or a kid and a dog. Everyone can sail the boat except the dogs.
How many one-way trips will they have to make to get everyone to the island
