Sally is going to the store to buy chocolate chip cookies for the class party. She sees a 16 oz. bag of cookies for $5.99 and a
Alex17521 [72]

Answer:

The 16 oz. bag for $5.99 is the better deal.

Step-by-step explanation:

We need to find the unit rate.

So a 16 oz. bag for $5.99, and a 22 oz. bag for $6.25.

All we need to do is divided the ounces by the prices.

16 divided by 5.99 is 2.67111853, rounded it's 2.70.

And 22 divided by 6.25 is 3.52

2.70 is way less than 3.52, so it's the cheapest and the better deal.
