Swifty, Inc. produces two types of gas grills: a family model and a deluxe model. Swifty'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: Total estimated overhead costs are $428,400. Overhead cost allocated to the machining activity cost pool is $257,040 and $171,360 is allocated to the machine setup activity cost pool. (a) Your answer is correct. Compute the overhead rate using the traditional (plantwide) approach. (Round answer to 2 decimal places, e.g. 15.25.) Overhead rate \$ Your answer is correct. Compute the overhead rates using the activity-based costing approach. (Round answers to 2 decimal places, e.g. 15.25.) Determine the difference in allocation between the two approaches
