Mariposa, Inc., produces machine tools and currently uses a plantwide overhead rate, based on machine hours. Harry Whipple departmental overhead rates can offer significantlv better cost assianments than can a plantwide rate. Mariposa has the fo lowing data for its two departments for the coming year: Department A Department B overnead costs expected) $600.000 $150.000 Normal activity (machine hours) 00 000 50.000 Reguired! 1. Compute a predetermined overhead rate for the plant as a whole based on machine hours 5 per machine hour 2. Compute predetermined overhead rates for each department using machine hours. Round your answers to one decimal place Departmend A ber machine nour Department B 3 V per machine hour 3. Suppose that a machine tool (Product X75) used 60 machine hours from Department A and 160 machine hours from Department B. A second machine tool (Product Y15) used 160 machine hours from Department A and 60 machine hours from Department B. Compute the overhead cost assigned to each product using the plantwide rate computed in Requirement 1. Product X75 Product Y15 Plantwide: 1,100 V 1,100 Repeat the computation using the departmental rates found in Requirement 2. Product X75 Product Y15 Departmental: 840 $ 1,140 V Which of the two approaches gives the fairest assignment? Departmental J 4. Repeat Requirement 3 assuming the expected overhead cost for Department B is $300,000. Product X75 Product Y15 Plantwide: Departmental
