The composition and energy content of a representative solid waste sample are given in the table. If the moisture content of the waste is $26 \%$, the energy content of the solid waste on dry-weight basis is ___________$\mathrm{MJ} / \mathrm{kg}$ (round off to one decimal place).
$$\begin{array}{|c|c|c|}
\hline \textbf{Component} & \begin{array}{c}\textbf { Percent by } \\
\textbf { mass }\end{array} & \begin{array}{c}\textbf { Energy content as-discarded basis } \\
\textbf{ (MJ/kg) }\end{array} \\
\hline \text{Food waste} & 20 & 4.5 \\
\hline \text{Paper} & 45 & 16.0 \\
\hline \text{Cardboard} & 5 & 14.0 \\
\hline \text{Plastics} & 10 & 32.0 \\
\hline \text{Others}& 20 & 8.0 \\
