Dwyran Ltd. manufactures 3 components Alpha, Bravo and Charlie, on its new machine which has 60,000 hours available, with the 3 components being used to produce Delta which is a relatively new product and Dwyran Ltd. are trying to grow their market share. Dwyran Ltd. has orders for 5,000 units of each, from relatively established customers and Ruth is determined not to let these customers down. Other producers of the components have been sourced and Dwyran Ltd. are satisfied with the quality of these replacements and confident that they can buy them in if necessary.

The following information has been produced:

Each unit takes the following machine hours to make one unit of each component:
Alpha: 3 hours Bravo: 5 hours Charlie: 6 hours

The variable cost per unit of component is:
Alpha: £40 Bravo: £60 Charlie: £50

The buy in purchase cost of each component is:
Alpha: £44 Bravo: £66 Charlie: £65

In order to maximise their profits how many units of each component should the company produce or buy in?

Determine the inventory cost under each of the following methods.

a. Determine the inventory cost by the first-in, first-out method.
$

b. Determine the inventory cost by the last-in, first-out method.

Appendix: Normal and Abnormal Spoilage in Process Costing, Changes in Output Measures, Multiple Departments

Grayson Company produces an industrial chemical used for cleaning and lubricating machinery. In the Mixing Department, liquid and dry chemicals are blended to form slurry. Output is measured in gallons. In the Baking Department, the slurry is subjected to high heat, and the residue appears in irregular lumps. Output is measured in pounds. In the Grinding Department, the irregular lumps are ground into a powder, and this powder is placed in 50-pound bags. Output is measured in bags produced. In April, the company reported the following data:

The Mixing Department transferred 50,000 gallons to the Baking Department, costing $250,000. Each gallon of slurry weighs two pounds.
The Baking Department transferred 100,000 pounds (irregular lumps) to the Grinding Department. At the beginning of the month, there were 5,000 gallons of slurry in process, 25 percent complete, costing $35,000 (transferred-in cost of $25,000 plus conversion cost of $10,000). No additional direct materials are added in the Baking Department. At the end of April, there was no ending work in process. Conversion costs for the month totaled $205,000. Normal loss during baking is 5 percent of good output. All transferred-in materials are lost, but since loss occurs uniformly throughout the process, only 50 percent of the conversion units are assumed to be lost.
The Grinding Department transferred 2,500 bags of chemicals to its finished goods warehouse. Beginning work in process for this department was 25,000 pounds, 40 percent complete with the following costs: transferred-in cost, $132,500; conversion cost, $15,000. Bags are used at the end of the process and cost $1.50 each. During bagging, normally one out of every 11 bags is torn and must be discarded. No powder is lost (the tearing occurs when the bag is being attached to a funnel). Conversion costs for the month's production are $172,500. There is no ending work in process.

Required:

1. Using FIFO, calculate the cost per bag of chemicals transferred to the finished goods warehouse. Round per-unit costs to the nearest cent. Round all other answers to the nearest unit or dollar, if required.

    Problem Set 6.6: Independent Samples t Test

    Criterion: Identify IV, DV, and hypotheses and evaluate the null hypothesis for an independent samples t test.

    Data: Use the information from Problem Set 6.5.

    Instruction: Complete the following:

11.    Identify the IV and DV in the study.
12.    State the null hypothesis and the directional (one-tailed) alternative hypothesis.
13.    Can you reject the null hypothesis at α = .05? Explain why or why not.

Albany has recently spent some time on researching and developing a new product for which they are trying to establish a suitable price. Previously they have used cost-plus 20 per cent to set the selling price.

The standard cost per unit has been estimated as follows:

Required:

1. Using the standard costs calculate two different cost-plus prices using two different bases and explain an advantage and disadvantage of each method.

2. Give two other possible pricing strategies that could be adopted and describe the impact of each one on the price of the product.
