10. (10 points) Draw the societal PPF for pens and paper that would combine the productions of Darrin, Henry, Frank, and Tracy. The table below shows their individual productions of each good separately, assuming they spent all their time producing just that one good. Be sure to label your axes, each segment of the societal PPF (by attaching a name to it), endpoints, and all middle points where the slope changes (i.e., where a "kink" in the graph occurs).
