Answer:
$9,325
Explanation:
The computation of Incremental net operating income(loss) is shown below:-
Per unit Total 5500 units
Incremental revenue $27.70 $152,350
Incremental costs
Direct materials $2.95 $16,225
Direct labor $8.25 $45,375
Variable manufacturing
overhead $7.35 $40,425
Increase in variable costs $4 $22,000
Purchase of special tool $19,000
Total Incremental costs $143,025
Incremental net operating income(loss) $9,325
Therefore the incremental income is $9,325
