Best Buys

The best buy is the item that gives you the most for your money, found by comparing unit prices. In NSW Year 7 maths this is a practical use of rates, such as dollars per kilogram or per 100 g (NESA outcome MA4‑RAT‑C‑01).

You will change every item to the same unit, divide price by quantity, round to the nearest cent, compare and write a clear conclusion, work out the saving between two options, and take off any discount first. Reading supermarket shelf labels and judging “3 for $6.60” deals use exactly these skills. This subtopic is part of Year 7 Ratios, Rates and Time.
