X Company currently makes a part and is considering buying it next year from a company that has offered to supply it for $17.53 per unit. This year, total costs to produce 65,000 units were: Direct materials Direct labor Variable overhead Fixed overhead $455,000 377,000 266,500 266,500 If X Company buys the part, $26,650 of the fixed overhead is avoidable.
