Given:
Total students = 24
Bottles required for each student = 4
Part A:
1 student needs 4 bottles of water.
24 students will need
![\begin{gathered} =24*4 \\ =96\text{ } \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/nh0deqa2rr40xqs1xz527irgp1nrykv15w.png)
Hence, 96 bottles are required.
Part B:
Since there are 12 bottles in one package
Therefore, 96 bottles will make
![\begin{gathered} =(96)/(12) \\ =8 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/ydrmcesulw86dt0nebm52yahzdm75taqz1.png)
So, the packages required will be 8.
