At a supermarket, you can buy a six pack of 500ml bottles of a fruit drink for £3, or a 2 litre bottle of the same fruit drink for £2.25. Jamie wants to buy 6 litres of the fruit drink. What should he buy to get the best deal?
To find the best deal, we need to compare the cost per litre for both options.
For the six pack of 500ml bottles, Jamie would need to buy 12 bottles (6 packs x 2 bottles per pack) to get 6 litres. The cost would be £3 x 2 = £6.
For the 2 litre bottle, Jamie would need to buy 3 bottles (6 litres / 2 litres per bottle) to get 6 litres. The cost would be £2.25 x 3 = £6.75.
Therefore, Jamie should buy the 2 litre bottles as it would cost him £6.75, which is cheaper compared to buying the six pack for £6. Therefore, Jamie should buy the 2 litre bottles to get the best deal.
