Calculating breakeven point for two products, margin of safety, andoperating leverage
The contribution margin income statement of Delectable Donuts for May 2018follows:
DELECTABLE DONUTS Contribution Margin Income Statement Month Ended May 31, 2018 |
Net Sales Revenue | \(125,000 | |
Variable cost | ||
Cost of goods sold | \)32,100 | |
Selling cost | 17,400 | |
Administrative cost | 500 | \(50,000 |
Contribution Margin | \)75,000 | |
Fixed cost | ||
Selling cost | \(37,800 | |
Administrative cost | 12,600 | \)50,400 |

Delectable sells five dozen plain donuts for every dozen custard-filled donuts. A dozenplain donuts sells for \)4.00, with a variable cost of \(1.60 per dozen. A dozen custardfilled donuts sells for \)8.00, with a variable cost of $3.20 per dozen.
Requirements
1. Calculate the weighted-average contribution margin.
2. Determine Delectable’s monthly breakeven point in dozens of plain donuts and custard-filled donuts. Prove your answer by preparing a summary contribution nmargin income statement at the breakeven level of sales. Show only two categories of costs: variable and fixed.
3. Compute Delectable’s margin of safety in dollars for May 2018.
4. Compute the degree of operating leverage for Delectable Donuts. Estimate thenew operating income if total sales increase by 20%. (Round the degree of operating leverage to four decimal places and the final answer to the nearest dollar.Assume the sales mix remains unchanged.)
5. Prove your answer to Requirement 4 by preparing a contribution marginincome statement with a 20% increase in total sales. (The sales mix remainsunchanged.)
Question: Use the following information to complete Short Exercises S20-10 through S20-15.

Calculating breakeven point in units, contribution margin ratio given
Ocean Company sells a product with a contribution margin ratio of 80%. Fixed costs are \(2,800 per month. What amount of sales (in dollars) must Ocean Company have to break even? If each unit sells for \)30, how many units must be sold to break even?
Question: Determining fixed cost per unit
For each total fixed cost listed below, determine the fixed cost per unit when sales are 50, 100, and 200 units.
