A supermarket sells boxes of cereal in two sizes. Which box gives the best yet value for money? You must show your working.

Question

Regular: 450g costing £1.80

Large: 600g costing £2.45

Answer 1

Determine the value by calculating the cost per gram.

Regular cereal costs 1.80/450 = 0.0033 £/g

Large cereal costs 2.45/600 = 0.0041 £/g

So the large cereal is a better value.
