Data table 25,000 hours $ 300,000 3,500 hours Practical capacity Fixed costs of the Engineering Services Department in the 9,000 labour-hour to 25,000 labour-hour relevant range Budgeted usage (quantity) of engineering services labour- hours required to support the productions departments: Machining Department Assembly Department Total Budgeted variable cost per engineering services labour-hour in the 9,000 labour-hour to 25,000 labour-hour relevant range Actual usage quantity) of engineering services labour-hours required to support the production departments: Machining Department Assembly Department 6,500 hours 10,000 hours 45 per hour used 3,000 hours 6,000 hours 9,000 hours Total Atkin Corporation has one support department, Engineering Services, and two production departments, Machining and Assembly. The following data relate to the 2017 budget for the Engineering Services Department. Click the icon to view the budget data for 2017.) Required Requirement 1. Using the single-rate method, calculate the cost to be allocated to the Machining and Assembly Departments if the allocation rate is based on budgeted costs and budgeted quantity of Engineering Services and allocated based on actual Engineering Services hours used in each department. Begin by determining the rate per hour used to allocate Engineering Services Department costs to the Machining and Assembly Departments. Budgeted total rate per hour is $ 75 Now, we can allocate the engineering-services costs to the Machining and Assembly Departments under the single-rate method. Machining department: $ 225,000 Assembly department: $ 450,000 Requirement 2. Using the dual-rate method, calculate the cost to be allocated to the Machining and Assembly Departments if (a) variable costs are allocated based on the budgeted variable cost per hour for actual hours used in each department and (b) fixed costs are allocated based on budgeted fixed costs per hour and the budgeted number of hours for each department. Before completing the allocation, calculate the budgeted fixed cost rate per hour. Budgeted fixed cost rate per hour is $ 30 Requirement). Using the single rate method. calculate the cost to be located to the Machining and Assembly Departments in the allocation rate is based on budgeted costs and practical capacity of Engineering Services Department and allocated based on actual Engineering Services hours used in each department Begin by determining the budgeted total-cost rate per hour (Round your answer to the nearest cont.) Budgeted total contrate per hour iss Now, we can allocate the engineering-services costs to the machining and assembly departments under the single-rate method, based on actual hours used in each department. Machining department Assembly department Requirement. Using the dual-cate method, calculate the cost to be allocated to the Machining and Assembly Departments if(s) variable costs are allocated based on the budgeted variable cost per hour for actual hours used in each department and (b) the feed-cost allocation rate is based on budgeted costs and practical capacity of Engineering Services Department and allocated based on budgeted Engineering Services hours used in each department Begin with the Machining Department Fed costs Variable costs Total costs Now. allocate the costs to the Assembly Department Fedot Variable costs Total costs
