Which cost accounting classification describes costs that combine both fixed and variable cost components?

Explanation

• Semi-Variable (Mixed) Costs contain a fixed base cost plus a variable component that changes with usage (e.g., utility bills, phone plans).
• High-Low Method and Regression Analysis are standard techniques used to split mixed costs into fixed and variable elements.
• Total mixed cost formula: $Y = a + bX$, where $a$ is fixed cost and $b$ is variable rate per unit.
