Gum is on sale. You can get 50 packages for $6.99 at the Candy Store, 40 pieces for $5.75 at Sweet Treats or 25 pieces for $4.25 at Chew-chew's. Where will you buy your gum for the best buy?

The Candy Store

Step-by-step explanation:

In order to find the best buy, we have to find the unit price for each store. The first store we will look at is the Candy Store. To find unit prices, we must divide the price by the number of merchandise for sale, as shown here:

6.99 / 50 = 0.1398

This means each piece of gum costs a little less than 14 cents.

Moving on to Sweet Treats:

5.75 / 40 = 0.14375

Each piece of gum at this store costs a little more than 14 cents.

Last but not least, Chew-Chew's:

4.25 / 25 = 0.17

Each piece of gum here costs 17 cents.

Now, to determine which price is better, we have to go with the lowest unit price, which would be at the first shop, the Candy Store, which is your answer.

Hope this helps :)
