Man O$$Fort Inc. produces two different styles of door handles, standard and curved. The door handles go through a joint production molding process costing $$32,000$ per batch and producing $2,400$ standard door handles and $1,200$ curved door handles at the split$-$off point. Both door handles undergo additional production processes after the split$-$off point, but could be sold at that point: the standard style for $$10$ per door handle and the curved style for $$5$ per door handle.
