Problem 17-28 Service Department Cost Allocation; Plantwide versus Departmental Overhead Rates; Cost Drivers (LO 17-1, 17-2, 17-3) [The following information applies to the questions displayed below.] Travelcraft Company manufactures a complete line of fiberglass suitcases and attach cases. The firm has three manufacturing departments: Molding, Component, and Assembly. There are also two service departments: Power and Maintenance. The sides of the cases are manufactured in the Molding Department. The frames, hinges, and locks are manufactured in the Component Department. The cases are completed in the Assembly Department. Varying amounts of materials, time, and effort are required for each of the cases. The Power Department and Maintenance Department provide services to the three manufacturing departments. Travelcraft has always used a plantwide overhead rate. Direct-labor hours are used to assign overhead to products. The predetermined overhead rate is calculated by dividing the company's total estimated overhead by the total estimated direct-labor hours to be worked in the three manufacturing departments. Karen Mason, director of cost management, has recommended that Travelcraft use departmental overhead rates. The planned operating costs and expected levels of activity for the coming year have been developed by Mason and are presented by department in the following schedules. (All numbers are in thousands.) Required: 1. Calculate the plantwide overhead rate for Travelcraft Company for the coming year using the same method as used in the past. (Round your answer to 2 decimal places.)
