Final answer:
Property insurance premiums are most likely to be a fixed cost.
Step-by-step explanation:
Fixed costs are expenditures that do not change regardless of the level of production. One example of a fixed cost is property insurance premiums. These premiums remain the same regardless of the volume of products produced or sold. Shipping charges, on the other hand, would typically vary with the volume of goods shipped and are therefore considered a variable cost. Wages for unskilled labor can also vary depending on the number of laborers employed, making it a variable cost. Expenditures for raw materials are also likely to be variable as they would increase or decrease depending on the production volume.
