Answer:
D. $5.00 cost per unit.
Step-by-step explanation:
The computation of the incremental cost or saving of purchasing the component is shown below;
Selling price = $32
And, the making cost is
= Direct material + direct labor + variable overhead
= $10 + $14 + $3
= $27
So, the net incremental cost is
= Selling price - making cost
= $32 - $27
= $5 cost per unit
Hence, the correct option is d.
