Reducir, Inc., produces two different types of hydraulic cylinders. Reducir produces a major subassembly for the cylinders in the Cutting and Welding Department. Other parts and the subassembly are then assembled in the Assembly Department. The activities, expected costs, and drivers associated with these two manufacturing processes are given below.

The per unit overhead cost using the 14 activity-based drivers is $1,108 and $779 for Cylinder A and Cylinder B, respectively.

Required:

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	$
Machining	$
Setups	$

Calculate the total activity costs of all the three activities.

	Cost pools
Welding	$
Machining	$
Setups	$

	Activity Rates
Welding	$	per welding hour
Machining	$	per machine hour
Setups	$	per batch

Now assign these total costs to the products using the drivers of the three chosen activities.

	Cylinder A		Cylinder B
Rate 1 (welding)	$		$
Rate 2 (machining)	$		$
Rate 3 (setups)	$		$
Total overhead costs	$		$
Unit overhead costs	$		$

3. Using the costs assigned in Requirement 2, calculate the percentage error using the ABC costs as a benchmark. Round your answers to one decimal place. If an item is negative, use a minus (-) sign to indicate.

	Percentage error
Cylinder A	%
Cylinder B	%
