From the provided schedule of activity costs, determine the non-value-added costs.

B) $50,000
C) $64,000
D) $85,000

Non-value-added costs are those that do not contribute to the customer's perception of value. These costs can often be reduced or eliminated without affecting the quality or performance of the product or service. Without specific details on the activities and their associated costs, it's not possible to accurately determine which of the provided options represents non-value-added costs. However, if this question is based on a specific schedule of activity costs provided in a context not shared here, the correct answer would be based on identifying costs related to activities that do not directly contribute to producing a product or service valued by the customer.
