Smithson, Inc. produces two types of gas grills: a family model and a deluxe model. Smithson's controller has decided to use a plantwide overhead rate based on direct labor costs. The president of the company recently 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: Direct labor costs Machine hours Setup hours Family Model $75,600 2.000 200 Deluxe Model $151,200 2,000 800 Total estimated overhead costs are $453,600. Overhead cost allocated to the machining activity cost pool is $272.160 and $181.440 is allocated to the machine setup activity cost pool.
