3. KITE assembles products from component parts. It has two departments that process all products. During January, the beginning work in process in the assembly department was half complete as to conversion and complete as to direct materials. The beginning inventory included $12,000 for materials and $4,000 for conversion costs. Overhead is applied at the rate of 50% of direct manufacturing labor costs. Ending work-in-process inventory in the assembly department was 40% complete. All spoilage is considered normal and is detected at the end of the process. | | Assembly | Finishing | | --- | --- | --- | | Beginning work-in-process units | 20,000 | 24,000 | | Units started this period | 40,000 | ? | | Units transferred this period | 50,000 | 54,000 | | Ending work-in-process units | 8,000 | 20,000 | | Material costs added | $44,000 | $28,000 | | Direct manufacturing labor | $16,000 | $24,000 | (1). Prepare a production cost worksheet using weighted-average for the assembly department. (18%)

(2). Spoilage can be a significant cost for many organizations. Discuss when spoilage might happen and how the costs of normal spoilage get allocated. (4%)

4. ABC Company is interested in replacing a machine with a new one. The old machine has a salvage value of $20,000 now and no salvage value 3 years later, if rebuilt. If the old machine is kept, it must be rebuilt one year after at a predicted cost of $30,000. The new machine costs $120,000 and had a predicted salvage value of $25,000 at the end of three years. If purchased, the new machine will allow cash savings of $40,000 for the first year and $20,000 for each year of its remaining life. The cash savings all occur at the end of the respective year. Required: What is the net present value of purchasing the new machine if ABC Company has a required rate of return of 14%? (15%) 5. XYZ Company makes a special kind of television called HD. To produce HD, XYZ used $10,000,000 of assets at the beginning of 2018 and $14,000,000 of assets at the end of 2018. Other costs to produce HD are as follows: Direct materials $6,000 per unit Direct labor $100 per direct labor hour Indirect manufacturing cost $200 per machine hour The marketing costs for HD are $800,000 in 2018. During 2018, XYZ produced and sold 1,000 units of HD using 8,000 direct labor hours and 6,000 machine hours. HD is sold for $10,000 each. Required: (1). Assuming XYZ defines investment as average assets during the period, calculate the return on investment for HD. (10%)

(2). Calculate the residual income for HD if XYZ has a required rate of return of \(8\%\). (10%)

6. Taipei Company produces basketballs that it sells for $40 each. At capacity, Taipei can produce 60,000 units a year. The costs of producing and selling 60,000 units are as follows: | | Unit cost | Total costs | | --- | --- | --- | | Direct materials | $15 | $900,000 | | Direct labor | $4 | $240,000 | | Variable manufacturing overhead | $3 | $180,000 | | Fixed manufacturing overhead | $6 | $360,000 | | Variable marketing costs | $4 | $240,000 | | Fixed marketing costs | $3 | $180,000 | Required: Suppose Taipei Company is currently producing and selling 50,000 basketballs. Tainan Company wants to place a one-time only special order for 8,000 basketballs at $25 each. Taipei Company will not incur variable marketing costs for this special order. Should Taipei Company accept this order? Please show your calculations. (15%)
