Explain how you can compare the cost of two items that are different sizes.

Compare the cost for the each (smallest) unit.

Step-by-step explanation:

You can calculate the cost per unit

For example :

20 ounces of water of brand A cost 1.50

30 ounces of water of brand A cost 2

20 ounces of water cost 1.50/20 = 0.075 dollar per ounce

30 ounces of water cost 2/30 = 0.0677 dollar per ounce

First find the unit price for each. Then compare the unit prices. The item that has the lesser unit cost is the better buy.  

This was the example answer for this question, just add and move around the words to get a great unique answer. Hope this helps you!
