Final answer:
Direct costs that can be attributed to the finished product of a bus manufacturer include the wages paid to assembly-line production workers, the tires for buses, and the windshields for buses options(a,b,c), as these are direct labor and material costs directly involved in production.
Step-by-step explanation:
The question relates to the costs that are directly attributable to the finished product of a bus manufacturer. The costs directly attributable, also known as direct costs, are those that can be easily traced to the production of specific goods or services.
Options which are considered direct costs and directly attributable to the production of a bus include:
- The wages paid to assembly-line production workers: This is a direct labor cost, as these workers are directly involved in the manufacturing of the buses.
- The tires for buses: Tires are a direct material cost since they are an essential part of the finished product.
- The windshields for buses: Much like tires, windshields are a direct material cost and part of the end product.
However, the depreciation on factory building is not directly attributable to the finished product as it is considered an indirect cost. This cost is part of the factory's overhead, which is necessary for the production process but cannot be easily allocated to each unit produced.
