Answer:
-$8.30 per unit
Step-by-step explanation:
The computation of the net incremental cost or savings of buying the component is shown below:
Total making cost is
= $10.30 + $14.30 + $3.30 + $8.30
= $36.20
And, the relevant cost is
= $36.20 - $8.30
= $27.90
So, the increment cost for purchasing a component is
= $27.90 - $36.20
= -$8.30 per unit
The same is to be considered
