MacBook and MacBook Pro are two divisions at the Apple Group. The MacBook division manufactures batteries which it sells to other divisions and external customers. The MacBook Pro division has designed a new product with the name of MacBook Air, and has asked MacBook division to supply them with the battery component. Each unit of MacBook Air will require one battery component. This battery component will not be sold by MacBook to external customers. MacBook division has quoted a transfer price of R585 for each battery. It is the policy of Apple Group to reward managers based on their divisional returns on capital employed. Details of the monthly production for each division are as follows: MacBook division Output Variable cost Fixed costs Battery components will be produced in batches of 1000 units. R195 per battery R60 000 (these are incurred to produce the battery component) MacBook Pro division Output Variable costs Fixed costs MacBook Air will be produced in batches of 1000 units The maximum customer demand is 6000 units. R117 per unit plus the cost of the Battery component. R75 000 (there are incurred specifically to produce MacBook Air. The relationship between monthly customer demand and the selling price of MacBook Air is shown below: Demand 1000 units selling price per unit R1 560 2000 units R1 430 3000 units R1 300 4000 units R1 170 5000 units 6000 units R1 040 R871 Required: 4.1.
