Question

Elena spent $2.50 on pineapple juice. Pineapple juice costs $0.10 per ounce. How many ounces of pineapple juice did Elena buy?

Answer 1

Elena bought `25` ounces of pineapple juice.

Explanation:

We know that however many ounces of pineapple juice Elena bought must equal to the `$2.50` she spent.
We also know that it costs `$0.10` per ounce.

Let's let `x` be the number of ounces of pineapple juice that Elena bought:

`0.10x = 2.50`

To solve this, we need to find `x` by itself. To do so, we divided both sides of the equation by `0.10`.

We get:
`x = 25`

Elena bought `25` ounces of pineapple juice.
