best buy - Harris Girls' Academy East Dulwich

What is best buy??
Best buy is when you are given certain prices for
different amount of products and you have to
decide which one has the cheapest value.
To find the best buy you have to divide the
product price by the number of products it has
The pack of 35 cost £600
The pack of 3 cost £12
£600 35= 13.14
Each chocolate bar in the £600 pack cost £13.14
£12 3=4
Each chocolate bar in the 3 pack cost £4
So the 3 pack one is cheaper and you get more
for your money than the other one. So if you
buy the 3 pack one you save your money.
