Unit Price Mrs. Kuznia Math 8 Day 7 What is Unit Price? Unit price is the cost of one unit of measure of an item. Unit price is often used in a grocery store to compare the price of two or more brands of the same item. How do we determine Unit Prices? To determine a unit price we will set up a proportion.

Find the Unit Cost if a 10 oz bottle of Baby Shampoo Costs $1.89 Comparing Unit Prices Sometimes, we want to compare the unit prices of two different items.

A 12 oz can of Campbells Tomato Soup for $0.99, or a 10 oz can of Heinz Tomato Soup for $0.89 Which is the better buy? A 12 pack of pop-tarts for $2.99 or an 8 pack of pop-tarts for $2.19? Try One!
