Relevant Costing
Problem 1: Northern Company incurs the following costs per unit in producing 500,000 units of product N-1: Variable manufacturing cost $5.00 Sales Commission $1.00 Fixed manufacturing cost $2.00 Fixed non-manufacturing cost $1.00 Total Cost per unit $9.00 The normal selling price for N-1 is $10.00 per unit. Southern Company has placed a special order with Northern to buy 10,000 units for $7.00 per unit. The production and sale to Southern would not displace any regular sales of N1, and no sales commissions would be paid on Southern's order. Northern is operating about the break-even point. By how much would the profit of Northern increase or decrease if Southern's order is accepted? Problem 2: Chicago Company manufactures part no. 118 for use in the production of its final product. The costs per unit for 10,000 units of part no. 118 are as follows: Direct materials $4.00 Direct labour $24.00 Variable overhead $10.00 fixed overhead applied $8.00 Total costs per unit $46.00 New York Company has offered to sell Chicago Company 10,000 units of part no. 118 for $43 per unit. If Chicago Company accepts the offer, some of the facilities presently used to manufacture part no. 118 could be used to manufacture part no. 119. This would save $40,000 of relevant costs in the manufacture of part no. 119, and $3 per unit of fixed overhead applied to part no. 118 would be eliminated. By what amount would net relevant costs be increased or decreased if Chicago Company decides to buy part no. 118 from New York Company? Problem 3: Star Company has obsolete light fixtures in inventory with manufacturing cost of $60,000. The company can rework the fixtures for $20,000 and then sell them for $36,000. Alternatively, it can sell them as scrap for $12,000. Which alternative should Star Company choose? Problem 4: Computer Company manufactures 10,000 units of part C-1 annually for use in the production of minicomputers. The following costs are incurred at 10,000 units of production: Direct materials $20,000 Direct labour $50,000 Variable overhead $40,000 Fixed overhead $80,000 Total Cost $190,000 Disk Drive Company has offered to sell 10,000 units of C-1 to Computer Company for $14 per unit. If Computer Company accepts this offer, some of the facilities presently used to manufacture C-1 could be rented to a third party at an annual rental of $16,000. Should Computer Company accept Disk Drive Company's offer? Problem 5: Southeast Company has an annual plant capacity of 2,000 units of product X, and the plant is currently operating at 50% of capacity (i.e., 1,000 units). Southeast is operating above the break-even point. Annual costs at a production level of 1,000 units are as follows: Variable manufacturing cost $10 per unit Fixed manufacturing cost $5 per unit Variable selling cost $1 per unit Fixed selling and administrative costs $5,000 per year The normal selling price per unit for product X is $25. Central Company has offered to buy 100 units of product X for $20 per unit. The sale of 100 units to Central Company would not displace any normal sales of product X. Southeast Company would incur variable selling costs of $1 per unit for the sale of 100 units. There is no alternative use for the idle capacity at Southeast Company in the short run. Should Southeast Company accept Central Company's offer?

Problem 6: Micro Company currently manufactures 20,000 units of part #15 at the following costs: direct materials $120,000, direct labour, $600,000, variable overhead, $240,000, and fixed overhead, $300,000 Alpha Company offers to manufacture part no. 15 for Micro Company for $60 per unit. If Micro accepts Alpha's offer, Micro will eliminate $180,000 of fixed overhead. In addition, Micro will able to rent for $85,000 per year the factory capacity presently used in the production of part no. 15. Should Micro accept Alpha's offer? Problem 7: A truck with a cost of $20,000 is totally destroyed during its first day of use. Unfortunately, the truck was uninsured. The truck can be sold as scrap for $3,000 cash and replaced with a new truck costing $20,500, or it can be rebuilt for $16,000. Which alternative should be selected? Problem 8: Digit Company currently buys 5,000 units of subcomponent part for $20 per unit. The management of Digit feels that some of the company's idle capacity can be utilized to produce the part in-house. Following are the estimated costs of manufacturing the subcomponent. Per unit Total Direct materials $5.00 $25,000 Direct labour $10.00 $50,000 Variable overhead $2.00 $10,000 Fixed overhead $5.00 $25,000 Total costs $22.00 $110,000 Assuming that there is no opportunity cost of using its idle capacity, and no additional fixed overhead costs will be incurred if the part is made in-house, should Digit Company make or buy the subcomponent part? Problem 9: Big city Motors is trying to decide whether it should keep its existing car washing machine or purchase a new one that has technological advantages (which translates into cost savings) over the existing machine. Information on each machine follows: Old Machine New Machine Original Cost--------------------------------------- $10,000 $20,000 Remaining Life------------------------------------- 10 yrs 10yrs Accumulated depreciation------------------------ $5,000 0 Annual cash operating costs---------------------- $9,000 $4,000 Current salvage value of old machine----------- $2,000 Salvage value in 10 years------------------------- $500 $1,000 Problem 10: K Co. uses 10,000 units of part in its production process. The cost to make a part is: direct materials, $12; direct labour, $25; variable overhead, $13' and applied fixed overhead, $30. K Co. has received a quote of $55 from a potential supplier for this part. If K Co. buys the part, 70% of the applied fixed overhead would continue. K Co. would be better off by? Problem 11: P Co. only has 25,000 hours of machine time each month to manufacture its two products. Products X has a contribution margin of $50 and Product Y has a contribution margin of $64. Product X requires 5 hours of machine time and Product Y requires 8 hours of machine time. If P wants to dedicate 80% of its machine time to the product that will provide the most income, P will have a contribution margin of? Problem 12: Down Co. has 3 divisions: R, S, and T. Division R's income statement shows the following for the year ended December 31, 1990. Sales---------------------------------------------------------------------------------$1,000,000 Cost of Goods Sold----------------------------------------------------------------$ 800,000 Gross Profit-------------------------------------------------------------------------$ 200,000 Selling Expenses----------------------$100,000 Administrative expenses-------------$250,000 $ 350,000 Net Loss-----------------------------------------------------------------------------$(150,000)

Cost of Goods Sold is 75% variable and 25% fixed. Of the fixed COGS, 60% is avoidable if the division is closed. All of the selling expenses are variable. Of the administrative expenses (all of which are fixed), 90% are an allocation of head office costs so that only 10% could be avoided. Show whether the company would be better off to eliminate Division R. Problem 13: Sandow Co. is currently operating at a loss of $15,000. The sales manager has received a special order for 5,000 units of product, which normally sells for $35 per unit. Costs associated with the product are normally: direct materials, $6; direct labour, $10; variable overhead, $3; applied fixed overhead, $4; and variable selling expenses, $2. The special order would allow the use of a slightly lower grade of direct material, thereby lowering the price per unit by $1.50 and selling expenses would be decreased by $1. If Sandow wants this special order to increase the total net income for the firm to $10,000, what sales price must be quoted for each of? Problem 14: Q Co. produces a part which has the following costs per unit: Direct materials $8.00 Direct labour $3.00 Variable overhead $1.00 Fixed overhead $5.00 Total $17.00 Z Corp. can provide the part to Q for $19/unit. Q Co. has determined that 60% of its fixed overhead would continue if it purchased the part. However, if Q no longer produces the part, it can rent that portion of the plant facilities for $60,000/year. Q Co. currently produces 10,000 parts/year. Which alternative is preferable and by what margin? Problem 15: Armstrong Co. has 15,000 units in inventory that had a production cost of $3/unit. These units cannot be sold through normal channels due to a significant technology change. These units could be reworked at a total cost of $23,000 and sold for $28,000. Another alternative is to sell the units to a junk dealer for $8,500. Show the relevant cost analysis to indicate what decision Armstrong should make. Problem 16: Refer to the information in the preceding problem, and assume that R has sufficient idle capacity to produce the 1,000 units. If R wants to increase its operating profit by $5,600 it would charge a per unit selling price of? Problem 17: Handy Combs, Inc. makes and sells brushes and combs. It can sell all of either product it can make. The following data are pertinent to each respective product: Brushes Combs Units of output/machine hour 8 12 Selling price/ unit $12 $1 Product cost/ unit Direct materials $1.00 $0.20 Direct Labour $2.00 $0.10 Variable overhead $0.50 $0.05 Total fixed overhead is $380,000. The company has 40,000 machine hours available for production. What sales mix will maximize profits? Problem 18: Boston Shoe Cobblers has been asked to submit a bid on supplying 1,000 pairs of military dress boots to the Pentagon. The company's costs per pair of boots are as follows: Direct Materials $8.00 Direct Labour $6.00 Variable overhead $3.00 Variable selling cost (commission) $3.00 Fixed overhead (allocated) $2.00 Fixed selling and administrative cost $1.00 Assuming that there would be no commission on this potential sale, the lowest price the firm can bid is some price greater than?
