Explanation:
1. Rent on unused factory space is an opportunity cost as when the factory space is used for the purpose of manufacturing a new product the company will have to forego its rental income. This is also a differential cost as when factory space is used for own purpose the rental income is lost.
2. Depreciation on factory space is a fixed cost as the amount will be fixed per year under the straight line method. It is also a product cost as it will be a part of factory overhead. Lastly it will be a differential cost as this cost would not have been there if factory space is given on rent.
3. Direct materials and direct labor are variable costs and depends on quantity manufactured. They are product costs as well as they are incurred while manufacturing the product.
4. Rental cost of small warehouse is a fixed cost as it entails a fixed expense of $2,000 per month. The warehouse is used for storing finished goods and so it will not be a product cost but a period costs. It will also be a part of selling and administrative expenses as the warehouse stores finished goods and hence help in the sale of finished goods later on.
5. Advertising cost is also a fixed cost as it entails a fixed expense of $4,000 per month. This cost helps to promote the product and increase its sales and hence it is also a selling expense.
6. Production supervisor’s salary s also a fixed cost as it entails a fixed expense of $3,000 per month. This cost is a product cost as it will be regarded as an indirect labor cost and hence will be a part of factory overhead.
7. Sales commissions are a variable cost as it is directly related to number of units sold. This cost helps to augment sales and hence it is also a selling expense.
