Blinky is blowing up balloons for a birthday party.
The number of blown up balloons of each colour is recorded in the table below.
\begin{array} {|l|c|}
\hline
\rule{0pt}{2.5ex} \textbf{Colour} \rule[-1ex]{0pt}{0pt} & \textbf{Number of Balloons} \\
\hline
\rule{0pt}{2.5ex} \text{white} \rule[-1ex]{0pt}{0pt} & 11 \\
\hline
\rule{0pt}{2.5ex} \text{purple} \rule[-1ex]{0pt}{0pt} & 7 \\
\hline
\rule{0pt}{2.5ex} \text{orange} \rule[-1ex]{0pt}{0pt} & 6 \\
\hline
\rule{0pt}{2.5ex} \text{yellow} \rule[-1ex]{0pt}{0pt} & 9 \\
