The overhead cos t allocated to the machining activity cost pool is $177 and $1 is allated to the machine set-up activity cost pool. Instructions (a) Calculate the overhead rate using the traditional (plant-wi&) approach. (b) Calculate the overhead rate using the activity-based costing approach Determine the differee in allation the two approhes.
