A new energy drink advertises 120 calories for 5 oz.
How many calories are in 15 oz?
We can set up a proportion to solve this problem
[tex]\frac{120}{5}=\frac{x}{15}[/tex]Where x is the number of calories in 15 oz
Let us solve the above equation for x
[tex]\begin{gathered} \frac{120}{5}=\frac{x}{15} \\ \frac{x}{15}=\frac{120}{5} \\ x=\frac{120}{5}\cdot15 \\ x=120\cdot3 \\ x=360 \end{gathered}[/tex]Therefore, there are 360 calories in 15 oz of drink.
