Let J be the number of pages that John reads. Then:


J=28

Now, we have that Lisa reads 4 times as many as John, then we have:


L=4J

Then, the expression to find the total number of pages that Lisa read is:


\begin{gathered} J=28 \\ L=4J \\ \Rightarrow L=\text{ 4x28=112} \end{gathered}

therefore, Lisa reads 112 pages
