Quizplus · Accepted Answer

The total cost of making the harnesses in-house is $17,000 ($5 variable cost per unit * 800 units + $13,000 fixed costs). Outsourcing would cost $8,000 ($10 per unit * 800 units). Since fixed costs are unavoidable, outsourcing would result in a lower total cost and higher operating income.
