Sunland Inc. makes two types of handbags: standard and custom. The controller has decided to use a plant-wide overhead rate based on direct labour 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 (machine hours) and machine set-up (number of set-ups). The total estimated machine hours is 1.500, and the total estimated number of setups is 500. Presented below is information related to the company's operations. Standard Custom Direct labour costs $50,000 $100,000 Machine hours 500 1,000 Set-up hours 100 400 Total estimated overhead costs are $315,000. The overhead cost allocated to the machining activity cost pool is $178.500, and $136,500 is allocated to the machine set-up activity cost pool (a) Calculate the overhead rate using the traditional (plant-wide) approach Predetermined overhead rate % of direct labour cost
