Answer:
Differential income from further processing $ 4.05

A company should process further a product if the additional revenue from the split-off point is greater than than the further processing cost.
Also note that all cost incurred up to the point of crush are irrelevant to the decision to process further
Revenue from unfinished desk = $65.00
Revenue from finished desks 75.00
Additional revenue from further process 10
Further processing cost 5.95
Differential income from further processing 4.05
