CDF is a manufacturing company within the DF group. CDF has been asked to provide a quotation for a contract for a new customer and is aware that this could lead to further orders. As a consequence, CDF will produce the quotation by using relevant costing instead of its usual method of full cost plus pricing. The
following information has been obtained in relation to the contract: Material D 40 tons of material D would be required. This material is in regular use by CDF and has a current purchase price of $38 per ton. Currently, there are 5 tons in inventory which cost $35 per ton. The resale value of the material in inventory is $24 per ton.
Components 4,000 components would be required. These could be bought externally for $15 each or alternatively they could be supplied by RDF, another company within the DF manufacturing group. The variable cost of the component if it were manufactured by RDF would be $8 per unit, and RDF adds 30% to its variable cost to contribute to its fixed costs plus a further 20% to this total cost in order to set its internal transfer price. RDF has sufficient capacity to produce 2,500 components without affecting its ability to satisfy its own external customers. However, in order to make the extra 1,500 components required by CDF, RDF would have to forgo other external sales of $50,000 which have a contribution to sales ratio of 40%.
Labour hours 850 direct labour hours would be required. All direct labour within CDF is paid on an hourly basis with no guaranteed wage agreement. The grade of labour required is currently paid $10 per hour, but department W is already working at 100% capacity. Possible ways of overcoming this problem are:
* Use workers in department Z, because it has sufficient capacity. These workers are paid $15 per hour.
* Arrange for sub-contract workers to undertake some of the other work that is performed in department W.
The sub-contract workers would cost $13 per hour.
Specialist machine The contract would require a specialist machine. The machine could be hired for $15,000 or it could be bought for $50,000. At the end of the contract if the machine were bought, it could be sold for
$30,000. Alternatively, it could be modified at a cost of $5,000 and then used on other contracts instead of buying another essential machine that would cost $45,000. The operating costs of the machine are payable by CDF whether it hires or buys the machine. These costs would total $12,000 in respect of the new contract.
Supervisor The contract would be supervised by an existing manager who is paid an annual salary of $50,000 and has sufficient capacity to carry out this supervision. The manager would receive a bonus of $500 for the additional work.
Development time 15 hours of development time at a cost of $3,000 have already been worked in determining the resource requirements of the contract.
Fixed overhead absorption rate CDF uses an absorption rate of $20 per direct labour hour to recover its general fixed overhead costs. This includes $5 per hour for depreciation.
Calculate the relevant cost of the contract to CDF. You must present your answer in a schedule that clearly shows the relevant cost value for each of the items identified above. You should also explain each relevant cost value you have included in your schedule and why any values you have excluded are not relevant.
Ignore taxation and the time value of money.
Select all the true statements.

• A. Development Cost is a relevant cost.
• B. The total relevant cost was $104 320
• C. Machine operating costs is a relevant cost.
• D. The total relevant cost was $94 740
• E. The total relevant cost was $84 990
• F. Direct labour cist is a relevant cost
• G. General fixed overhead costs are relevant costs.

A company is preparing its annual budget and is estimating the number of units of Product A that it will sell in each quarter of year 2. Past experience has shown that the trend for sales of the product is represented by the following relationship:
y = a + bx where
y = number of sales units in the quarter a = 10,000 units b = 3,000 units x = the quarter number where 1 = quarter 1 of year 1 Actual sales of Product A in Year 1 were affected by seasonal variations and were as follows:
Quarter 1:14,000 units Quarter2: 18,000 units Quarter 3: 18,000 units Quarter 4: 20,000 units Calculate the expected sales of Product A (in units) for each quarter of year 2, after adjusting for seasonal variations using the additive model.

• A. The expected sales for year 2 Quarter 4 was 40000 units
• B. The expected sales for year 2 Quarter 4 was 32000 units
• C. The expected sales for year 2 Quarter 4 was 33000 units
• D. The expected sales for year 2 Quarter 4 was 32700 units

THS produces two products from different combinations of the same resources. Details of the products are shown below:

Identify, using graphical linear programming, the optimal production plan for products E and R to maximize THS's profit in the month.

• A. The solution (from the graph0 is to produce 475 units of E and 770 units of R.
• B. The solution (from the graph0 is to produce 375 units of E and 870 units of R.
• C. The solution (from the graph0 is to produce 495 units of E and 470 units of R.
• D. The solution (from the graph0 is to produce 375 units of E and 750 units of R.
• E. The solution (from the graph0 is to produce 495 units of E and 670 units of R.
• F. The solution (from the graph0 is to produce 675 units of E and 470 units of R.

A company produces three products D, E and F. The statement below shows the selling price and product costs per unit for each product, based on a traditional absorption costing system.

Each of the products is produced using Process A which has a maximum capacity of 2,500 hours per period.
If a traditional contribution approach is used, the ranking of products, in order of priority, for the profit maximizing product mix will be:

• A. D, E, F
• B. E, D, F
• C. F, D, F
• D. D, E, F
