Last year, the company sold 33,500 balls, with the following results: Sales (33,500 balls) Variable expenses Contribution margin Fixed expenses Net operating income Required: $ 837,500 502,500 335,000 229,600 $ 105,400 1. Compute (a) last year's CM ratio and the break-even point in balls and (b) the degree of operating leverage at last year's sales level. 2. Due to an increase in labor rates, the company estimates next year's variable expenses will increase by $3 per ball. If this change takes place and the selling price per ball remains constant at $25, what will be next year's CM ratio and the break-even point in balls? 3. Refer to the data in requirement 2. If the expected change in variable expenses takes place, how many balls will have to be sold next year to earn the same net operating income, $105,400, as last year? 4. Refer again to the data in requirement 2. The president feels that the company must raise the selling price of its basketballs. If Northwood Company wants to maintain the same CM ratio as last year (as computed in requirement 1a), what selling price per ball must it charge next year to cover the increased labor costs? 5. Refer to the original data. The company is discussing the construction of a new, automated manufacturing plant. The new plant would slash variable expenses per ball by 40.00%, but it would cause fixed expenses per year to double. If the new plant is built, what would be the company's new CM ratio and new break-even point in balls? 6. Refer to the data in requirement 5. a. If the new plant is built, how many balls will have to be sold next year to earn the same net operating income, $105,400, as last year? b. Assume the new plant is built and that next year the company manufactures and sells 33,500 balls (the same number as sold last year). Prepare a contribution format income statement and compute the degree of operating leverage.
