Answer a-d please and thanks

Question 4 Total 20 marks Australasian Ltd. produces two types of desks that are classified into two types as in-door and Out- door. The company uses a simple job-costing system that has two direct-cost categories (direct materials and direct labour). Regarding indirect costs, the company uses a single indirect-cost pool of machine hours to allocate the indirect cost. For 20XX, Australasian Ltd estimates its manufacturing overhead costs of $240,000 and 8,000 machine hours. Australasian collected the following information for 20XX. Indoor Outdoor Number of desks 300 desks 200 desks Machine hours per desk 10 hours 10 hours Price per desk $900 $1,300 Cost of materials per desk $200 $300 Direct labour costs per desk $180 $410 Required: (a) Using the simple costing system, calculate the product cost per unit for the Indoor (5 marks) and Outdoor desk. (b) Assumed Australasian Ltd. incurred actual total manufacturing costs of $242,000 (2 marks) and 8,000 total machine hours during the year. Determine the amount of under applied or over applied manufacturing overhead for the period and prepare a journal entry to close any balance in the manufacturing overhead account assuming the under/over applied overhead amount is insignificant. (c) Australasian Ltd is concerned about the accuracy of the costs assigned to indoor and Outdoor desk and therefore is planning to implement an activity-based costing (ABC) system. Australasian's ABC system would have the same direct-cost categories as its simple costing system. However, instead of a single indirect-cost pool there would now be three categories (design, setup and printing machine operations) for assigning indirect costs. To see how activity-based costing would affect the costs of Indoor desk or Outdoor desk, the following information is collected for an analysis. Activity Costs Allocation Quantity of Cost Allocation Base Base Executive desk Elite desk Design $100,000 Design hrs 800 design hrs 3,200 design hrs Setups 65,000 No of setups 10 setups 40 setups Machine 75,000 Machine hrs 3,000 machine hrs 2,000 machine hrs operations Using the activity-based costing system, calculate the estimated product cost per (8 marks) unit for Indoor and Outdoor desk. (d) Compare the result of the costs of Indoor and Outdoor desk under a simple and an (5 marks) activity-based costing system. Explain why they are different (use the figure of your result as part of your arguments)
