TCB Ltd manufactures three lines of TV monitors: M101, M102 and M103. TCB currently uses a traditional, volume-based costing system, where overhead cost allocation is based on the number of monitors produced. The CFO is contemplating changing to an Activity Based Costing (ABC) system, as has asked for your assistance in considering this. The following information has been provided for the month of June 20X4: Traditional costing information, from the existing costing system, is presented below:

M101 M102 M103 Total

Number of monitors produced 800 600 600 2,000

$ $ $ $

Prime costs 710,000.00 660,000.00 780,000.00 2,150,000.00

Manufacturing overhead 75,600.00 56,700.00 56,700.00 189,000.00

Total manufacturing cost 785,600.00 716,700.00 836,700.00 2,339,000.00

Cost per unit 982.00 1,194.50 1,394.50
