Concept explainers

In layman's terms, variance analysis is an analysis of a difference between planned and actual behavior. Variance analysis is mainly used by the companies to maintain a control over a business. After analyzing differences, companies find the reasons for …

Standard Costing

The standard cost system is the expected cost per unit product manufactured and it helps in estimating the deviations and controlling them as well as fixing the selling price of the product. For example, it helps to plan the cost for the coming year on t…

Textbook Question

Chapter 10, Problem 10.29E

Learning curve, incremental unit-time learning model. Assume the same information for Northern Defense as in Exercise 10-33, 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.

Required

2. If you solved Exercise 10-33, 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?
