1. Determine the percentage of total costs represented by the three most expensive activities. % 2. If required, round your interim calculations and final answers to the nearest dollar. Allocate the costs of all other activities to the three activities identified in Requirement 1 in proportion to their individual activity costs. Allocation Welding $ 352,941 Machining $ 176,471 Setups 70,588 Calculate the total activity costs of all the three activities. Welding Machining Setups Cost pools 2,352,941 1,176,471 470,588 Activity Rates Welding $ 588 per welding hour Machining $ 118 per machine hour Setups 4,706 per batch. Now assign these total costs to the products using the drivers of the three chosen activities.
