To solve this worksheet, we need to
calculate the unit price for each option (price per single item), then
compare them to find the
better buy — the one with the
lower unit price.
---
✔ General Rule:
>
Unit Price = Total Price ÷ Number of Items
The option with the
smaller unit price is the
better buy.
