Total cost is calculated by adding fixed costs to variable costs. Fixed costs are expenses that do not change with the level of production or sales, such as rent, salaries, and insurance. They remain constant regardless of how much product is made or sold. On the other hand, variable costs fluctuate with production volume, including costs for materials, labor, and shipping that increase as more goods are produced.

The total cost represents the complete expenditure required to manufacture a product or provide a service and is vital for businesses to understand their pricing strategies, profitability, and overall financial health.

Therefore, when calculating total cost, combining both fixed and variable costs gives businesses the full picture of their expense structure, which is essential for budgeting and financial planning. The other options do not accurately represent the relationship between costs in a business context, as they either misinterpret cost components or provide calculations that do not derive total cost.
