We have a question on conversion of units, in this case, pints to ounces.
1 pint = 16 ounces
Each student had 1 pint,
Total volume by 14 students = 14 x 1 = 14 pints.
Next we convert to ounces:
[tex]\begin{gathered} 1\text{ pint = 16 oz} \\ 14\text{ pints = 14 }\times16=224\text{ ounces} \end{gathered}[/tex]The class consumed 224 ounces
