Looking For the Better Buy
Ingrid was looking for new hair ties to buy. She looked at bundles of hair ties from Walmart and Walgreen's. These are the price tags.
In Walmart, Ingrid found that a bundle of 30 hair ties would cost $3.87.
In Walgreen's, Ingrid found that a bundle of 28 hair ties would cost $3.19.
Which Item Is the Better Buy?
Calculating the Unit Rate
To find which item is the better buy, Ingrid calculated the unit rates for the cost per hairband. The unit rate is helpful to compare prices for different items.
The Better Buy Is...
Once Ingrid calculated the unit rates of each item, she found that buying hair bands from Walgreen's was the best buy, since each hair band cost once cent less than each Walmart hair band.
