Best buys

If there is more than one deal on offer, how do I work out which deal is best?

  • Find the price of 1 item (by dividing the number of items and total price by the same scale factor)

    • E.g. If 3 tins cost £1.20 then 1 tin costs 40p (by dividing both quantities by 3)

  • Compare the prices of 1 item from each shop / deal to see which is cheaper

    • The cheaper deal is the better value for money

    • E.g. 1 tin costs 40p from shop A and 45p from shop B

      • 1 tin at shop A is cheaper than at shop B

      • Shop A is therefore the better value for money

  • For more complicated deals, write down each line of working clearly

Worked Example

Two deals for buying caps are given below:

3 caps for £22.50 from Baseball World
5 caps for £36 from Head Hut

At which shop are the caps better value? 
You must show your working.

Find the cost of 1 cap from Baseball World (by dividing £22.50 by 3)

22.50 ÷ 3 = £7.50 for 1 cap from Baseball World

Find the cost of 1 cap from Head Hut (by dividing 36 by 5)

36 ÷ 5 = £7.20 for 1 cap from Head Hut

Compare the price of 1 cap from each shop to see which is cheapest

£7.20 is cheaper than £7.50

Write down, with reason, the shop with better value

1 cap from Head Hut costs £7.20 and 1 cap from Baseball World costs £7.50
£7.20 is cheaper than £7.50 so Head Hut is better value
