I need section A, section D & section E Natha Corporation manufacturers two types of travel mugs: Simple, and Sophisticated. The company budgets to produce 20,000 units of the Simple mugs and 10,000 units of the Sophisticated mugs. Manufacturing takes place in two production departments: Machining and Assembly. The Simple mugs are produced in batches of 200 units; however, due to the more intricate detail included on the Sophisticated mugs, they are produced in batches of 50 units. 3 The companys Controller has asked you to compare the plantwide, departmental, and activitybased cost allocation methods. To assist in your analysis, the Controller has provided you with the budgeted cost information for the 2020 fiscal year. Natha Budgeted Information for the Year Ended December 31, 2020 Machining Department Simple Sophisticated Total Direct materials cost $90,000.00 $52,500.00 $142,500.00 Direct labour cost 45,000.00 30,000.00 75,000.00 Overhead costs 120,000.00 Machine hours 12,000 18,000 30,000 Direct labour hours 4,000 1,000 5,000 Assembly Department Simple Sophisticated Total Direct materials cost $7,500.00 $15,000.00 $22,500.00 Direct labour cost 22,500.00 37,500.00 60,000.00 Overhead costs 40,000.00 Machine hours 6,000 4,000 10,000 Direct labour hours 3,500 500 4,000 Required: (A) Assume that the corporation is using a single plantwide overhead rate based on machine hours. a.
