Soutn Pacific regions. The company has two Divisions, the Engine Division and Assembly Division. The final products of the Engine Division are used as the engine in assembling the car parts. The following data is available for the two Divisions: Engine Division 150500500=1500.3x350=15000.3x=350.67dx=1166.50xx - At a market price of M500, there is currently no demand for engines - However, demand increases by 200 units for every M60 reduced from the price. - The variable cost per engine is M150 - There are no capacity constraints Assembly Division MRENM2=15046x=150. - At a market price of M700 there is currently no demand for the finished truck produced - However, demand increases by 400 units for every M100 reduced from the price. - The variable cost per truck is M200 (excluding the cost of the engine) Equations to use for calculations are: P=abxMR=a2bx a) find the optimum number of units to be made by the Parts Division and the optimal price to be charged (5marks) b) based on the above engine price, find the optimum number of trucks to be made by assembly division (4marks) c) Find the optimum number of vehicles and price that will maximise the Group's profits (6marks) d) Differentiate between Economic Value Added (EVA) and Return on Investment (ROI) as measures for divisional performance and give ONE advantage and disadvantage of each.
