=+3-36 KK Cost estimation, incremental unit-time learning model OBJECTIVE 6 Assume the same information for Nautical Ltd as in Problem 3-35 with one exception. This exception is that Nautical Ltd uses a 90%

incremental unit-time learning model as a basis for predicting direct manufacturing labour-hours in its assembling operations. (A 90%

learning curve means b = –0.152004.)

Required 1 Prepare a prediction of the total costs for producing the six PT109s for the navy.
