Soni Limited manufactures headphones which can be used on smart phones and tablets have recently adopted ABC (Activity based costing) to allocate overhead costs. Soni Limited manufactures two models of headphones to cater for two different markets. Model 100 has basic functions, while Model 200 is a more sophisticated model which is wireless and includes blue tooth connectivity, noise cancelling and a closed back earcup design to reduce low frequency interference. The following overhead cost pools and activity drivers have been determined by management. Overhead Cost Pool Activity Driver Budgeted Overhead Cost $200,000 Number of setups Machine set-ups Material handling $80,000 Number of units of raw materials used Waste control $40,000 kilos of waste $50,000 Number of inspections Quality control inspection Other overhead costs $175,000 Labour hours 12,000 units of MODEL 100 are produced which have the following production requirements: Activity Driver No of activities Number of setups 50 Set-ups 30,000 units Number of units of raw materials used Kilos of waste 200 kilos Number of inspections 40 inspections Labour hours 1,000 hours 5,000 units of MODEL 200 are produced, which have the following production requirements: Activity Driver No of activities Number of setups 30 Set-ups 20,000 units Number of units of raw materials used Kilos of waste 300 kilos Number of inspections 120 inspections Labour hours 400 hours Required 1. If Soni Limited used a single, predetermined overhead rate based on labour hours, calculate the overhead rate per unit to be assigned to each headphone model. Round all calculations and rates to 2 decimal places. (2 marks) 2. (0) If Soni Limited was to adopt Activity Based Costing (ABC) use the table below to calculate The total cost driver and allocation rate for each overhead cost pool The total overhead cost allocated to each model for each overhead cost pool The overhead cost per unit for each model.
