Use the high-low method to separate the mixed costs. Use labels to clearly indicate whether your answer is favourable (F) or unfavourable (U). If there is no variance, your answer should be zero (C) and the label should be "NONE'. Where applicable, round off the variable cost per unit to TWO decimal places. All unfavourable variances must be preceded by a minus sign eg -32000. Failure to adhere to these instructions will result in you forfeiting the mark for that
