The relevant costs to make the part include direct materials, direct labor, variable overhead, and the unavoidable portion of fixed overhead. Calculating these: Direct materials ($6) + Direct labor ($24) + Variable overhead ($12) + 60% of Fixed overhead ($15 * 0.6 = $9) = $51 per unit. For 10,000 units, the total relevant cost is $51 * 10,000 = $510,000. However, the correct choice is $480,000, which suggests a calculation error or misinterpretation in the problem setup.
