Identify each of the company's individual expenses as either a variable, fixed or mixed cost. 2. Using the high-low method, separate each of the individual mixed cost into the variable and fixed elements. State the cost equation for each individual mixed costs. 3. Edwards and Shaw expect to sell 6,500 units in October. Prepare an absorption income statement for October. 4. Prepare a Contribution Margin Income Statement based on October sales of 6,500 units. Do not combine expenses but show each expense separately in the appropriate category. 5. Calculate the contribution margin per unit and the variable cost ratio. 6. How many units would need to be sold to generate $350,000 in target income? (Round your answer to the nearest unit using the Excel Round Up function.) 7. Give one example of how Edwards and Shaw could increase projected operating income without increasing total sales revenue. 8. Edwards and Shaw are considering a multimedia advertising campaign that should increase sales by $50,000 per month. The ad campaign will cost an additional $1,500 per month and will be considered a fixed cost. How will the ad campaign affect product cost? How will the increase in fixed costs affect the break-even point? Explain.
