If the company decides to rework the units, its incremental income equals $20,000.
Incremental income represents the additional income gained after taking a decision, e.g. rework.
For instance, when this company reworks the units, it reduces its loss from $108,000 if the units were sold as scrap to $88,000.
Thus, the incremental income is the difference between $108,000 and $88,000 loss.
Defective units = 44,000
Cost of defective units = $264,000
Scrap value of defective units = $156,000
Cost of rework = $198,000
Sales value after rework = $374,000
Incremental income after rework =
Loss when sold as scrap = $108,000 ($264,000 - $156,000)
Loss when sold after rework = $88,000 ($374,000 - $264,000 - $198,000)
Incremental income after rework = $20,000 ($108,000 - $88,000)
Thus, if the company decides to rework the units, its incremental income equals $20,000.
