DETROIT FOUNDRY
             Cost per gallon
                         C23        U2
Unit  produced             500         300
Direct labor cost            $3,000       $8,000
Direct materials cost         28,000       18,000
machine set up cost            144          336
material handling cost          624          384
Machine operating cost         200         250
Total cost                   31,968        26,970
cost per gallon :
C23 Â = Â $31,968/500 = $63.94
U2 Â Â = Â $26,970/300 = $89.9
workings
machine set up per set up hour = $576,000/12,000 Â = Â $48
Material handling per material move = Â $96,000/2000 =$48
Machine operation per machine hour = Â $500,000/10,000 = $50
