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 haridling. 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 5,000 $2,500 High 20,000 2,500 Indirect labor Low 5,000 $53,000 High 20,000 107,000 Fuel and oil for forklift Low 5,000 $2,950 High 20,000 11,800 1 Required: 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
