Another company has offered to sell RootSystems the switch for $10.50 per unit. If RootSystems buys the switch from the outside supplier, none of the fixed costs are avoidable. The company prepared an outsourcing decision analysis to show the cost per unit of making the switches versus the cost per unit of buying (outsourcing) the switches. (Click the icon to view the outsourcing decision analysis.) RootSystems needs 83,000 optical switches next year (assume same relevant range). By outsourcing them, RootSystems can use its idle facilities to manufacture another product that will contribute $210,000 to operating income, but none of the fixed costs will be avoidable.
