Print answers as a table with the exam class

Question

Within the exam class i have been putting tables in for the people doing the questions to fill in the gaps. However when i write \printanswers i wish for the answers to appear within the table

---

\begin{table}[h]
\centering
\begin{tabular}{|l|l|l|}
\hline
\textbf{Item }  & \textbf{Full Price (£)} & \textbf{Sale Price (£)} \\ \hline
Shoes  & 25             &                \\ \hline
Jeans  & 40             &                \\ \hline
Socks  & 2              &                \\ \hline
Jumper & 17.50          &                \\ \hline
Suit   & 120            &                \\ \hline
\end{tabular}
\end{table}

But i wish the answers to appear red or something to clearly show that they are the solutions.

\begin{table}[h]
\centering
\begin{tabular}{|l|l|l|}
\hline
\textbf{Item }  & \textbf{Full Price (£)} & \textbf{Sale Price (£)} \\ \hline
Shoes  & 25             &        21.25        \\ \hline
Jeans  & 40             &     34           \\ \hline
Socks  & 2              &     1.70           \\ \hline
Jumper & 17.50          &        14.88        \\ \hline
Suit   & 120            &       102         \\ \hline
\end{tabular}
\end{table}
