Behavior of Variable and Fixed Costs:

Variable Costs: Describe how variable costs behave in total and on a per$-$unit basis. Provide examples to illustrate how these costs change with the level of production or sales volume.Fixed Costs: Explain how fixed costs behave in total and on a per$-$unit basis. Provide examples to demonstrate how these costs change with the level of production or sales volume.

High$-$Low Method and CVP Analysis:

High$-$Low Method: What is the high$-$low method used for, and how does it relate to CVP analysis? Explain the steps involved in using the high$-$low method to separate mixed costs into their variable and fixed components. Provide an example to illustrate the process.Relation to CVP Analysis: Discuss how the high$-$low method supports CVP analysis by helping to determine cost behavior and the impact of cost structure on profitability.

Contribution Margin Concepts in CVP Analysis:

Contribution Margin: Define contribution margin and explain its significance in CVP analysis.Unit Contribution Margin: Define unit contribution margin and describe how it is calculated and used in decision$-$making.Contribution Margin Ratio: Define contribution margin ratio and explain its role in CVP analysis.Break$-$Even Analysis: Discuss how contribution margin, unit contribution margin, and contribution margin ratio are used to determine the break$-$even point. Provide examples to demonstrate the calculations and interpretations.
