Assume that a batch of 60 throttle assemblies define one output unit and that the 38.46 factory labor hours is based on the 20th output unit. Assume a 90% learning curve slope. What was the number of factory labor hours required for the 1st batch of 60 throttle assemblies? (Assume that your final numerical answers is rounded off up to 2 decimal places and is in terms of labor hours.) What is your estimate of the labor hours needed for the 200th unit of output? (Assume that your final numerical answers is rounded off up to 2 decimal places and is in terms of labor hours.)
