Look at this price label for a 15 oz box of Cheerios cereal. The retail price for the cerealthe

price you and I pay in the grocery storeis $3.95. Note also that the store is required to

provide a unit price for the cereal. The unit price is 0.263 cents per ounce. You can see for

yourself where that unit price comes from:

$3.95 / 15 oz. = $ 0.263

Try it in your calculator for yourself! The good news is, you don't need to carry a calculator to

the grocery store and do this math for yourselfNY State law requires the store to label their

prices this way. Every product in the product category (in this case, cereal) is required to be

priced on a common basis (in this case, per ounce), so that consumers can make easy

comparisons across different brands and sizes that are offered. If you look at unit prices, you

can determine which product is the most cost effective.

Now imagine that this grocery store also has a 28 oz box of Cheerios with a retail price of $6.95.

1) What is the unit price for this box of Cheerios?

2) Which sizethe 15 oz. or the 28 oz.is the better value for consumers? In other

words, which box is cheaper on a per-ounce basis?

3) The grocery store has a store brand called O'Cheeries! It is sold in a 10 oz box at a retail

price of $2.99. If you don't care about brand name, and are going to make your decision

totally on the best value for your money, which option should you choose:

10 oz O'Cheeries, 15 oz Cheerios, or 28 oz Cheerios?
