Watch the assumption for cost behavior patterns used in cost-volume-profit analysis with its corresponding explanation. Your choices are: - All costs can be classified as either fixed or variable. - There is a constant product mix, - There is a linear relationship between cost and revenue. - Only volume affects total cost and total revenue. - Production volume is equal to sales volume. Match each of the options above to the items below. Determine the total fixed and variable costs per unit (including for mixed costs); step costs remain fixed within the relevant range. Even if a company makes and sells multiple products, we assume the relative proportion of units sold remains the same. Use a straight line to approximate the relationship between total cost and sales volume and between total revenue and sales volume
