Answer:
$7.50 per unit
Step-by-step explanation:
Cost of buying from outside supplier = $33 per unit.
Relevant cost of making such component in-house = Direct materials+ Direct labor+ Variable overhead
= $9.50 per unit + $13.50 per unit + $2.50 per unit
= $25.50 per unit
Net incremental cost of buying the component = Cost of buying from outside supplier- Relevant cost of making such component in-house
= $33.00 per unit - $25.50 per unit
= $7.50 per unit
