Do you need a unit rate? Or do you have an attatchment for me to solve the unit rate? If you need an example of a unit rate one could be:
27 gallons.
----------------
$3. Cost
27 divided by 3 is 9
9 gallons
-------------
Per dollar
I believe the answer is 136.5g
Well the answer of how many printers does the store sell is 16
so it would be 2 8 16
