(20 marks) Question 6 Victory Yacht Company (Victory) has designed a new model of yacht. The Company uses 80% cumulative average-time learning model to forecast the manufacturing labour time to make a yacht. The estimated manufacturing data of the first yacht are: $300,000 per unit 500 direct labour hours $50 per direct labour hour $80 per direct labour hour Direct materials cost Direct manufacturing labour time Direct manufacturing labour cost Variable manufacturing overhead cost Victory's management team expects that the time required to make a yacht will diminish as the production team masters the necessary building techniques Note: For an 80% learning curve, b In0.81n0.2--0.322 Required: (a) (b) What would be the total costs for the first Calculate the total costs of the first four yachts.

Compare the results of requirement prediction different? How should Victory decide which model it should use? (c) s (a) and (b). Why is the (4 marks)
