Robert is not satisfied with the traditional method of allocating overhead because he believes that most of the overhead costs relate to the truck wheel product line because of its complexity. He therefore develops the following three activity cost pools and related cost drivers to better understand these costs: Estimated Overhead Costs Activity Cost Pools Estimated Use of Cost Drivers Setting up machines $530,000 1,000 set-ups Assembling 370,000 37,000 labour hours Inspection 720,000 1,440 inspections Calculate the activity-based overhead rates for these three cost pools. Cost Pool Rate Setting up machines $ per set-up Assembling $ per labour hour Inspection $ per inspection
