The median is the middle value when the data is arranged in order from least to greatest. In this case, the data can be arranged as:$\begin{array} { l l l l l l l l l l } \hline 11.99 & 14.00 & 16.40 & 21.65 & 29.51 & 30.04 & 32.07 & 33.42 & 39.46 & 41.60 \42.16 & 42.22 & 42.34 & 43.02 & 43.97 & 44.80 & 45.22 & 46.61 & 47.81 & 49.39 \\hline\end{array}$The middle value is 42.16, so the median price for these purchases is $42.16.
