TSS Company is noted for its full line of quality lamps. The company operates one of its plants in TARLAC. That plant produces two types of lamps: classical and modern. JD,the president of the company, recently decided to change from a unit-based, traditional costing system to an activity-based costinf system. Before making the change companywide, she wanted to assess the effect on th product cost of the TARLAC plant. This plant was chosen because it produces only two types of lamps; most other plants produce at least a dozen. To asses the effect of the change, the following data have been gathered (for simplicity, assume one process): Under the current system, the costs of operating equipment, materials handling and set-ups are assigned to the lamps on the basis of machine hours. Lamps are produced and moved in batches. How much is the difference in total unit cost of classical lamp between traditional and ABC costing system ?

How much is the difference in total unit cost between ABC and traditional costing of modern lamp ?
