Required: 2, 3 & 4. Compute the activity overhead rates using ABC. Combine the grinding and polishing activities into a single cost pool. Determine overhead costs to assign to the above jobs using ABC. What is the overhead cost per unit for Job 3175? What is the overhead cost per unit for Job 4286? (Round your activity rate and average overhead cost per unit to 2 decimal places. Round "overhead assigned" to the nearest whole dollar.)
