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

`(120)/(5)=(x)/(15)`

Where x is the number of calories in 15 oz

Let us solve the above equation for x

`\begin{gathered} (120)/(5)=(x)/(15) \\ (x)/(15)=(120)/(5) \\ x=(120)/(5)\cdot15 \\ x=120\cdot3 \\ x=360 \end{gathered}`

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