    Full Answer

    B.$5,000 advantage✓ Correct
    A
    Relevant Costs to Make (Avoidable): $50,000 (DM) + $40,000 (DL) + $20,000 (VOH) + $10,000 (Fixed) = $120,000.<br/>Opportunity Cost of Making (Rent forgone): $5,000.<br/>Total Cost to Make: $125,000.<br/>Cost to Buy: $120,000.<br/>Advantage to Buy: $125,000 - $120,000 = $5,000.

    Common mistakes

    Including unavoidable fixed costs; ignoring opportunity cost.
