Crane Matthew, the controller of Inca Industries, has prepared an analysis to help management determine whether one of Inca's departments should be eliminated. The department's contribution margin is $68000. The fixed expenses charged to the department total $98000. Of the fixed expenses, Matthew estimates that $47000 of those expenses would be eliminated if the department were discontinued. Based on Matthew's analysis, if the department is eliminated, Inca's overall operating income would decrease by $21000 per year. O increase by $21000 per year. decrease by $17000 per year. O decrease by $30000 per year
