The rest of manufacturing overhead should be allocated by an appropriate allocation base following a typical job-order costing method. The production supervisor examined the results of past operations to find the allocation base for the manufacturing overhead. She believes that a measure that best explains the changes in manufacturing overhead should be the allocation base.
