High-Low Method, Cost Formulas

The controller of the South Charleston plant of Ravinia, Inc., monitored activities associated with materials handling costs. The high and low levels of resource usage occurred in September and March for three different resources associated with materials handling. The number of moves is the driver. The total costs of the three resources and the activity output, as measured by moves for the two different levels, are presented as follows:

Resource		Number of Moves		Total Cost
Forklift depreciation:
Low		5,500		$1,900
High		17,500		1,900
Indirect labor:
Low		5,500		$78,800
High		17,500		146,000
Fuel and oil for forklift:
Low		5,500		$4,840
High		17,500		15,400

If required, round your answers to two decimal places. Enter a "0" if required.

1. Determine the cost behavior formula of each resource. Use the high-low method to assess the fixed and variable components.

Forklift depreciation:
V	$
F	$
Y	$
Indirect labor:
V	$
F	$
Y	$ + $X
Fuel and oil for forklift:
V	$
F	$
Y	$X

2. Using your knowledge of cost behavior, predict the cost of each item for an activity output level of 7,000 moves.

3. Construct a cost formula that can be used to predict the total cost of the three resources combined. If required, round your answers to two decimal places. Materials handling cost = $ + $X

Using this formula, predict the total materials handling cost if activity output is 7,000 moves. Y = $
