The total cost of making the harnesses in-house is $17,800 ($4,800 variable + $13,000 fixed), while outsourcing would cost $9,600. However, since fixed costs are unavoidable, the relevant cost for decision-making is the variable cost, which is lower than the outsourcing cost. Therefore, Doro Fill should not outsource.
