Final answer:
The question relates to calculating total manufacturing overhead costs using standard costing at an activity level of 1,700 machine-hours, but without the proper overhead rates or a clear connection to the machine-hours stated, an accurate calculation cannot be provided.
Step-by-step explanation:
The question asks about the total manufacturing overhead costs at an activity level of 1,700 machine-hours using a standard costing system. While the question's details are not entirely provided, it seems to relate to calculations involving labor and machine costs at specified rates. To solve this, we need to consider the standard rates and then multiply these rates by the actual machine hours to get the total overhead costs. However, without the proper cost per machine-hour or labor cost per hour used in the scenario, we cannot provide an accurate answer. In standard costing, such totals would be calculated by adding fixed and variable overhead costs, both of which would be derived from the predetermined overhead rate and the actual activity level.
In the context given, we are talking about changes to cost due to negotiations with unions or changes in machine costs. Unfortunately, without the exact predetermined overhead rates or a clear connection to the 1,700 machine-hours, it's challenging to arrive at a specific total manufacturing overhead cost.
