Question 34

Machine maintenance, lease on factory, and plant supervisor salary are window costs.

Window costs in a construction company typically refer to the expenses that are not directly tied to production but are necessary for operations. In this case, machine maintenance, lease on factory, and plant supervisor salary fit this definition as they support the overall functioning of the business rather than the direct production of goods.

A) Lumber, production worker wages, and machine maintenance

This option is incorrect because while machine maintenance is a window cost, lumber and production worker wages are direct costs associated with production. These costs are not considered window costs as they contribute directly to the creation of products.

B) Production worker wages, machine maintenance, and lease on factory

This option is incorrect because production worker wages are a direct cost associated with labor for production. While machine maintenance and lease on factory are window costs, including production worker wages disqualifies this option from being correct.

C) Plant supervisor salary, lumber, and production worker wages

This option is incorrect as it includes lumber and production worker wages, both of which are direct costs related to production. Although the plant supervisor salary is a window cost, the presence of the other two makes this option incorrect.

D) Machine maintenance, lease on factory, and plant supervisor salary

This option is correct because all three costs listed are considered window costs. They are essential for the overall management and operation of the construction company but do not directly contribute to the production process.

Conclusion

The correct answer is option D, as it accurately identifies the three costs that function as window costs in a construction company. Options A, B, and C include direct production costs that do not meet the criteria for window costs, thereby confirming option D as the definitive choice.
