Publix has a 12 oz. box of Cheerios for $3.49. What is the unit rate per ounce?

Answers

Usually when in involves money, the format of the unit rate should be written as price per ______.

If we set up the rate given now, in a money/ounce format, it will be written like this:
$3.49 / 12 oz.

Because we're trying to find how much one ounce will cost (unit rate), we must divide $3.49 by 12 oz.

When dividing, you will get $0.29083....., which can be rounded to $0.29

The unit rate per ounce is $0.29.

Answer:

$3.49 / 12 oz.=0.29
