Problem:
Donkey Bikes could sell its bicycles to retailers either assembled or unassembled. The cost of an unassembled bike is as follows.
Direct material $150
Direct Labor 70
Variable overhead (70% of direct labor) 49
Fixed overhead (30% of direct labor ) 21
Manufacturing cost per unit $290
The unassembled bikes are sold to retailers at $400 each.
Donkey currently has unused productive capacity that is expected to continue indefinitely; management has concluded that some of this capacity can be used to assemble the bikes and sell them at $450 each. Assembling the bikes will increase direct materials by $5 per bike, and direct labor by $20 per bike. Additional variable overhead will be incurred at the normal rates, but there will be no additional fixed overhead as a result of assembling the bikes.
a) Prepare an incremental analysis for the sell-or-process-further decision.
b) Should Donkey sell or process further? Why or why not?
Please provide details for understand the exercise.
