How do I tell which of two prices is really cheaper?
You will learn how to compare two prices in a fair way.
Two prices are not always easy to compare. One box may be bigger. One may hold more.
The trick is to compare the price per unit. That is the price for one ounce, one pound, or one item.
ChatGPT can do this math for you. You tell it both prices and both sizes. It tells you the better deal.
This helps a lot at the store. A bigger box is not always the cheaper one.
Try this
- Write down the price and the size of each item.
- Open ChatGPT.
- Type both prices and both sizes.
- Ask which one costs less per unit.
- Pick the one with the lower price per unit.
A message you can copy
One bag is [price] for [size]. Another is [price] for [size]. Which is cheaper per ounce?
Paste it into ChatGPT, then change the words in brackets to fit you. It opens in a new tab, so you will not lose this page.

Some store shelf tags show "unit price" in small print. That number helps too.
