Your engineering department has just been told your 18 models of marine diesel engines must be redesigned for robot assembly. You estimate that the redesign of the first model will take 1,000 hours. Applying your departments history of an 80% learning rate for the first 8 units, what will be the total hours required to redesign all 18 models? Given an average employee rate of $250 per hour, what is the total cost for this redesign. Rubric (1 point each) Correct learning rate Correct per unit equation Correct learning curve limit Correct cumulative hours Correct total cost
