Calculate the total variable costs of producing 2, 3, and 4 units assuming that Global Defender uses an 85% Incremental unit-time learning model as a basis for predicting direct manufacturing labor-hours. Begin by calculating the cumulative total time in labor-hours using the incremental unit-time learning model. (Round the individual unit time for Xth unit to the nearest whole number.) Cumulative Individual unit time for Cumulative total time: number of units Xth unit: Labor-hours Labor-hours Now calculate the total variable costs of producing 2, 3, and 4 units.Variable costs of producing 2 Units 3 Units 4 Units Direct materials Direct manufacturing labor Variable manufacturing overhead Total variable costs Requirement 2. Compare the cost predictions from requirement 1 (incremental unit-time learning model) with the cost predictions of producing 2 and 4 units based on a cumulative average time learning model. Why are the predictions different? How should Global Defender decide which model it should use? Total variable costs for manufacturing 2 and 4 units are under the cumulative average-time learning curve relative to the incremental unit-time learning curve. Direct manufacturing labor-hours required to make additional units In the incremental unit-time learning curve relative to the cumulative average-time learning curve when the same 85% factor is used for both curves. The reason is that, in the as the number of units double only the last unit produced has a cost of 85%% of the initial cost. in the doubling the number of unita causes the cost of all the units produced (not just the last unit) to be 85% of the initial cost. How should Global Defender decide which model it should use? Managers should choose which model and what percent learning curve to use Engineers,Requirement 2. Compare the cost predictions from requirement 1 (incremental unit-time learning model) with the cost predictions of producing 2 and 4 units based on a cumulative average time learning model. Why are the predictions different? How should Global Defender decide which model it should use? Total variable costs for manufacturing 2 and 4 units are under the cumulative average-time learning curve relative to the Incremental unit-time learning curve Direct manufacturing labor-hours required to make additional units in the incremental unit-time leaming curve relative to the cumulative average time learning curve when the same 85%% factor is used for both curves, The reason is that. in the au tho number of units double only the last unit produced has a cost of 85%% of the initial cost. In the doubling the number of units causes the cost of all the units produced (not just the last unit) to be 85% of the Initial cost. How should Global Defender decide which model it should use? Managers should choose which model and what percent learning curve to use Engineers. plant managers, and workers of information on the amount and type of learning actually occurring. Plotting this information and estimating the model that best fos the data helpful to Global Defender when selecting the appropriate model.Data table Direct materials cost $ 82,000 per unit of RS-32 Direct manufacturing labor time for first unit 3,600 direct manufacturing labor-hours Learning curve for manufacturing labor time per radar system 85% incremental unit-time" Direct manufacturing labor costs S 20 per direct manufacturing labor-hour Variable manufacturing overhead costs S 17 per direct manufacturing labor-hour In 0.85 - 0.162519 "Using the formula for an 85% learning curve, b = = - 0.234465 In 2 0.693147 Print Done
