Question

A new energy drink advertises 120 calories for 5 oz. How many calories are in 15 oz of drink

Answer 1

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

$\frac{120}{5}=\frac{x}{15}$

Where x is the number of calories in 15 oz

Let us solve the above equation for x

$\begin{gathered} \frac{120}{5}=\frac{x}{15} \\ \frac{x}{15}=\frac{120}{5} \\ x=\frac{120}{5}\cdot15 \\ x=120\cdot3 \\ x=360 \end{gathered}$

Therefore, there are 360 calories in 15 oz of drink.
