Gonzalo sits down on the steps in front of his house with his clipboard and pencil and begins counting pickup trucks that go past. Gonzalo has to make a graph for his math class. Out of 18 pickup trucks, 17 have camper shells, 8 have CB antennas, and 7 have both. When he sits down to draw the graph, how many pickups belong in the group that has only camper shells, and how many belong in the group that has only CB antennas?
