Explanation:
Based on the information given, the relevant cost to make will be:
Direct Materials = $120,000
Add: Direct Labor = $25,000
Add: Variable Overhead = $45,000
Add: Fixed Overhead = $5,000
Relevant cost to make = $195,000
The relevant cost to buy is $190,000.
Therefore, the cost to buy is less as there'll be a net operating Income increase of $5000.
