The following information is avallable for a company's maintenance cost over the last seven months. Using the high-low method, estimate both the fixed and variable components of its maintenance cost. \begin{tabular}{l} Change in cost \\ Change in volume \\ Total cost \\ Total volume \\ \hline Total cost at the low point \\ \hline Variable costs at the low point: \\ \hline Volume at the low point: \\ \hline Variable cost per unit produced \\ \hline Total variable costs at the low point \\ \hline Total fixed costs \end{tabular} High-Low method - Calculation of variable cost per unit produ Cost at high point minus cost at low point Cost at low point minus cost at high point Volume at high point minus volume at low point Volume at low point minus volume at high point
