Zion Manufacturing had always made its components in-house. However, Bryce Component Works had recently offered to supply one component, K2, at a price of $25 each. Zion uses 12,000 units of Component K2 each year. The cost per unit of this component is as follows: Direct materials $12.00 Direct labor 8.25 Variable overhead 4.50 Fixed overhead Total 2.00 $26.75 Assume that 75% of Zion Manufacturing's fixed overhead for Component K2 would be eliminated if that component were no longer produced. Required: 1. CONCEPTUAL CONNECTION: If Zion decides to purchase the component from Bryce, by how much will operating income increase or decrease? Increase 21,000 X Which alternative is better? Purchase the component from Bryce 2. CONCEPTUAL CONNECTION: Briefly explain how increasing or decreasing the 75% figure affects Zion's final decision to make or purchase the component As the percentage of avoidable fixed cost increases (above 75%), total relevant costs of making the component increase, causing the "purchase" financially appealing (compared to the "make" option) than it was when the percentage was 75%. In other words, as decision to be more the percentage increases, difference between the "purchase" and "make" options increases resulting in the "purchase" decision being even more attractive. Alternatively, as the percentage of avoidable fixed costs decreases, the "make" option eventually is equally
