The Price of Just One
Divide the price by how many you get to find the cost of one.
The idea
The price on the tag only tells you what the whole package costs, not whether it is a good deal. To compare fairly, divide the price by how many you get, and that gives you the unit price, the cost of just one. A bigger package is often cheaper per unit, but not always, so it is worth checking. And the cheapest unit price is only a real bargain if you will actually use the whole thing ⚖️
