$\begin{array} { l c c } \\underline {\text { Month }} & \begin{array} { c } \text { Machine } \\\underline {\text { Hours }}\end{array} & \begin{array} { c } \text { Manufacturing } \\\underline {\text { Overhead }}\end{array} \\\text { August } & 46,000 & \$ 889,000 \\\text { September } & 60,000 & 1,130,000 \\\text { October } & 78,000 & 1,300,000 \\\text { November } & 62,000 & 1,000,000\end{array}$ October's costs consisted of machine supplies ($190,000), property taxes ($30,000), and plant maintenance ($1,080,000). These costs exhibit the following respective behaviour: variable, fixed, and semi-variable.
Required:
