From the information provided in the question, we can get a relationship between the number of calories and fluid ounces consumed:
[tex]c=15.2f[/tex]where
c = number of calories
f = amount of fluid ounces consumed.
QUESTION A
If Jeremy drinks 12 ounces, then we have that:
[tex]f=12[/tex]Therefore, the number of calories will be:
[tex]\begin{gathered} c=15.2\times12| \\ c=182.4 \end{gathered}[/tex]He consumes 182.4 calories.
QUESTION B
If Marlene consumes 252.84 calories, then we have that:
[tex]c=252.84[/tex]Therefore, the number of ounces consumed will be:
[tex]\begin{gathered} 252.84=15.2f \\ \therefore \\ f=\frac{252.84}{15.2} \\ f\approx16.6 \end{gathered}[/tex]She consumes approximately 16.6 ounces.
