Explanation:
[tex]\left[\begin{array}{cccc}-&East&West&Total\\Sakes&90,000&360,000&450,000\\Var.Exp&27,000&216,000&243,000\\CM&63,000&144,000&207,000\\Fixed Cost&46,800&54,000&100,800\\Fixed&&&72,000\\Inome&16,200&90,000&34,200\\\end{array}\right][/tex]
IF West Discontinued
-90,000 Income from Western Division
+10% CM East = 6,300
83,700
The traceable fixed cost will be eliminated if wester division is closed.
There is no data about unavoidable fixed cost, so it should be assumed all are eliminated.
