5. For the month of August, Purple Sun generated sales of $400,000. The company’s variable cost of goods sold for the month totaled $175,000, including variable overhead of $25,600. Total overhead for the month was $56,200. The company also incurred variable selling and administrative costs of $13,200 and fixed selling and administrative costs of $45,000. a.

During the month of May, Rosie’s Shoe Supply incurs the following costs: variable cost of goods sold, $18,000; fixed manufacturing costs, $4,000; variable selling and administrative, $1,400; and fixed selling and administrative, $2,200. The sales for the month totaled $43,000. Determine the company’s manufacturing margin, contribution margin, and income from operations for the month. 7. Finnegan’s produces 400 units for the month of September but only sells 325 units. Each unit incurs fixed manufacturing costs of $10 and variable manufacturing costs of $25. Determine the difference in variable costing and absorption costing, indicating which income will be higher. 8. Purple Sun produced 15,500 units of product during the last quarter. Due to a decrease in sales, the company sold only 13,600 of these products. To manufacture each unit, the company incurs fixed manufacturing costs of $12. Under absorption costing, the income from operations totals $72,900. Determine the income from operations under variable costing. 9. The Rarebit incurs fixed manufacturing costs of $600,000 to produce 150,000 units during the year. The company sold 142,400 of these units during the year to produce income from operations of $164,000, using the variable costing method. Determine the company’s income from operations using the absorption costing method. 10. Rosie’s Shoe Supply produces and sells 30,000 units during the year. The company also sells 2,000 of the beginning inventory. To produce each unit, Rosie’s Shoe Supply incurs fixed manufacturing costs of $12 per unit. Determine if income from operations will be higher under the variable or absorption costing method and the difference. 11. Poe’s Candles has inventory of 4,000 units at the beginning of the year. The company produced 22,000 units during the year and had no units on hand at the end of the year. The company incurred fixed manufacturing costs of $8 per unit.

12. Cutty’s Scissors generated an income from operations of $71,600 using the absorption costing method. The company sold 41,000 units, although it produced 39,200 units. The fixed manufacturing costs totaled $9 per unit, while variable manufacturing costs totaled $15 per unit. Determine the income from operations using the variable costing method. 13. Management of The Rarebit expects to sell 14,000 units for $12 each in the upcoming year and is deciding between producing 14,000 or 16,000 units. The company will incur variable costs of $4 per unit and total fixed costs of $21,000. The company also incurs fixed selling costs of $12,000 annually and incurs variable selling costs of $2 per unit. Prepare absorption costing income statements for the two options to determine how many units the company should produce to generate the highest income from operations. Round fixed manufacturing costs per unit to two decimal places. 14. Use the information in Exercise 13 to determine how many units the company should produce to generate the highest income from operations using variable costing income statements. 15. Finnegan’s expects to sell 53,000 units in the upcoming year. The production manager has decided the company can produce 53,000 products to meet the demand, or 58,000 products. The company will sell the units for $50 each and incur variable costs of $14 per unit. The company will also incur a variable selling expense of $5 per unit sold. Fixed costs include manufacturing costs of $41,000 and selling and administrative costs of $22,000. Using the absorption costing method, prepare the income statement for both situations to determine the number of units to produce if the company would like to generate the highest income from operations. Round fixed manufacturing costs per unit to two decimal places. 16. Assume the same information as Exercise 15, except that the company uses the variable costing method to determine income from operations. 17. After estimating unit sales to be 32,000 units for $35 each, Rosie’s Shoe Supply is trying to decide whether to produce 32,000 units or 36,000 units. The company will incur variable costs of $22 per unit and fixed manufacturing costs of $67,000. Each unit sold has a variable selling and administrative cost of $4.50. The fixed selling and administrative expenses will be $25,000. Use absorption costing income statements to determine the number of units to produce that will result in the highest income from operations. Round fixed manufacturing overhead per unit to two decimal places. 18. Use the information in Exercise 17 for Rosie’s Shoe Supply assuming the company calculates income from operations using the variable costing method to determine the number of units to produce.

19. The sales manager of a company is determining the best selling price for its new product. The manager expects that all costs incurred to make the product should be included in the decision. Should the manager use the variable or absorption costing method to determine the selling price? 20. In the past few years, a manufacturer has not produced sufficient units in order to meet the year’s sales. Management would like to produce enough products to meet demand and have an ending inventory. The company expects to incur additional fixed costs due to the increase in production. Should management use the variable or absorption costing method to determine the production planning for the upcoming years? 21. A manufacturing company promises a bonus to its production managers if they can increase profit in their department. Since the selling price is fixed, the managers must determine a way to decrease the costs to manufacture each unit. Would the variable or absorption costing method be more helpful to the managers? 22. Use the information below to calculate the contribution margin for the dog food and the Southern region. Pet Supply North South Sales volume (units): Dog food 15,000 19,200 Cat food 14,300 16,750 Sales price: Dog food $4.65 $4.50 Cat food $3.80 $3.95 Variable cost per unit: Dog food $2.80 $2.75 Cat food $1.15 $1.20
