The Shamrock Company uses standard costing for direct materials and direct labour. Management would like to use standard costing for variable and fixed overhead also. The following monthly cost functions were developed for manufacturing overhead items: OVERHEAD ITEM COST FUNCTION Indirect materials $0.10 per DLH Indirect labour $0.40 per DLH Repairs and maintenance $0.20 per DLH Utilities $0.25 per DLH Insurance $ 2,000 Rent $ 3,600 Depreciation $20,000 The cost functions are considered reliable within a relevant range of 30,000 to 55,000 direct labour hours. Shamrock expects to operate at 40,000 direct labour hours per month. Information for the month of September is as follows:Actual Overhead Costs Incurred: Indirect materials $4,510 Indirect labour 17,100 Repairs and maintenance 8,000 Utilities 10,000 Insurance 2,110 Rent 3,600 Depreciation $20,000 Total $65,320 Actual direct labour hours worked 42,000 Standard direct labour hours allowed for production achieved: 44,000Calculate the standard manufacturing overhead rate based upon expected capacity showing the breakdown between the fixed overhead rate and the variable overhead rate.
