Number of pages of notes taken by Marlon after attending 4 hours of class is 16 pages.
Solution:
Given that
Marlon took a total of 12 pages of notes during 3 hours of class.
Need to calculate total pages of notes after attending 4 hours of classes
Also given that relation between number of hours and number of pages is directly proportional.
Number of pages of notes in 3 hours = 12
So number of pages of notes in 1 hour =
![(12)/(3) = 4](https://img.qammunity.org/2020/formulas/mathematics/middle-school/fimriy90617wgz79utaqsy58w2pzou00j5.png)
So number of pages of notes in 4 hours = 4
number of pages of notes in 1 hour = 4
4 = 16 pages.
Hence number of pages of notes taken by Marlon after attending 4 hours of class is 16 pages
