Draw a behavioral state machine that describes thevarious states that a travel authorization can havethrough its approval process. A travel authorizationform is used in most companies to approve travelexpenses for employees. Typically, an employee fillsout a blank form and sends it to his or her boss for asignature. If the amount is fairly small ($300), then the boss signs the form andsends it to the CFO, along with a paragraph explain-ing the purpose of the travel; the CFO signs the formand passes it along to accounts payable. Of course,the boss and the CFO can reject the travel authori-zation form if they do not feel that the expenses arereasonable. In this case, the employee can change theform to include more explanation or decide to paythe expenses. D.
