Equate the ratio of serving of granola to the number of calories in two cases.
[tex]\begin{gathered} \frac{5}{1750}=\frac{g}{n} \\ n=\frac{1750\cdot g}{5} \\ n=350g \end{gathered}[/tex]Substitute 2.5 for g in the equation to obtain the value of n.
[tex]\begin{gathered} n=350\cdot2.5 \\ =875 \end{gathered}[/tex]So, number of caloreis in 2.5 serving of granola is 875.
