Answer:
$480,000
Explanation:
Calculation to determine what total relevant costs to make the part internally are
First step is to calculate Relevant cost per unit:
Relevant cost per unit:
Direct materials $6
Direct labor $24
Variable manufacturing overhead $12
Fixed manufacturing overhead ($15 × 0.40) $6
Relevant manufacturing cost $48
Now let determine the Total relevant costs to make the part internally
Total relevant costs to take the part internally=($48 × 10,000)
Total relevant costs to make the part internally = $480,000
Therefore total relevant costs to make the part internally are $480,000
