Total costs can be calculated by adding which two components?

• A. Operating costs and fixed costs
• B. Revenue and expenses
• C. Liabilities and equity
• D. Depreciation and amortization

Answer: (A)

Total costs are found by adding the costs that stay the same with production (fixed costs) to the costs that vary with activity (operating costs). Fixed costs are the constant expenses like rent or salaries that don’t change with how much you produce. Operating costs represent the day-to-day, variable expenses that rise or fall with production level, such as materials and utilities used in farming operations. By summing these two categories, you capture all the costs tied to running the operation in a given period.

Other options mix concepts that aren’t about totaling costs in a period: revenue and expenses relate to income and costs but aren’t two cost components added together to get total costs; liabilities and equity are financing sources, not cost components; depreciation and amortization are specific expense types but don’t alone represent all costs.
