Question

At the local grocery store, a 16-ounce bottle of apple juice costs $3.20. What is the cost of the apple juice per ounce?

Answer 1

The cost of apple juice per ounce is 20 cents.

Explanation:

We know that a `16` ounce bottle is `$3.20` and we want to find how much per ounce is.

So we set up a proportion and let `x` be the cost of one ounce:
`16/3.20 = 1/x`

Now we can cross multiply:
`16x = 3.20`

Divide both sides by `color(blue)16`:
`(16x)/color(blue)16 = 3.20/color(blue)16`

Therefore,
`x = 0.20`

The cost of apple juice per ounce is 20 cents.

Hope this helps!
