E4-1 Assign overhead using traditional costing and ABC. (LO 1, 2), AP Saddle Inc. has two types of handbags: standard and custom. The controller has decided to use a plant wide overhead rate based on direct labor costs. The president has heard of activity-based costing and wants to see how the results would differ if this system were used. Two activity cost pools were developed: machining and machine setup. Presented below is information related to the company's operations. Total estimated overhead costs are $240,000. Overhead cost allocated to the machining activity cost pool is $140,000, and $100,000 is allocated to the machine setup activity cost pool. Instructions (a) Compute the overhead rate using the traditional (plant wide) approach. (b) Compute the overhead rates using the activity-based costing approach. (c) Determine the difference in allocation between the two approaches
