Given that Alexandra read 12 books in 3 months.
The rate of reading here will refer to the time taken per book read by her.
This rate of reading can be calculated as follows,
![\begin{gathered} \text{Rate of reading}=\frac{\text{Total time taken }}{\text{ Total books read}} \\ \text{Rate of reading}=(3)/(12) \\ \text{Rate of reading}=0.25 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/j5dx1u93x7iwvu398n3ti0hkz2bsd6mu1s.png)
Thus, the rate of reading of Alexandra is 0.25 months per book.
The resized graph is shown below,
Thus, the rate of reading in months per book is plotted on the plane. So the two columns on the right side of the given graph should be resized to obtain the graph as shown above.
