Answer: B) Only materials costs are relevant
Step-by-step explanation:
When choosing between alternatives, the main decider is the difference in costs. The costs that are different are the ones to decide whether a company takes on a project as it will signal the financial viability of a project.
In both alternatives, the Processing costs remain at $37,000 therefore the alternative chosen is irrelevant to these costs as they will be incurred regardless of the company's choice. They are therefore not to be considered.
Material costs on the other hand vary by the alternatives and so should be considered.
