10-29 Learning curve, incremental unit-time learning model. Assume the same information for Northern Defense as in Exercise 10-28, except that Northern Defense uses an 85% incremental unit-time learning model as a basis for predicting direct manufacturing labor-hours. (An 85% learning curve means b = -0.234465.) Calculate the total variable costs of producing 2, 3, and 4 units. If you solved Exercise 10-28, compare your cost predictions in the two exercises for 2 and 4 units. Why are the predictions different? How should Northern Defense decide which model it should use?

10-29 Learning curve, incremental unit-time learning model. Assume the same information for Northern Defense as in Exercise 10-28, except that Northern Defense uses an 85% incremental unit-time learning model as a basis for predicting direct manufacturing labor-hours. (An 85% learning curve means b = -0.234465.)

  1. Calculate the total variable costs of producing 2, 3, and 4 units.
  2. If you solved Exercise 10-28, compare your cost predictions in the two exercises for 2 and 4 units. Why are the predictions different? How should Northern Defense decide which model it should use?
