Question

John read 28 pages of a book lisa read four times as many

Answer 1

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
