Question

a large pot cost 88 p of 822g and a small pot cost 47 p and weights 454g, which pot of jam is better value for money?

Answer 1

47 p for 454 g is a better value.

Explanation:

We find the unit costs by dividing each price by the corresponding weight.

88p for 822 g

unit cost = (88p)/(822 g) = 0.1070559 p/g

47p for 454 g

unit cost = (47p)/(454 g) = 0.1035242 p/g

Since 0.1035 < 0.1070, the second choice is a better value.

Answer: 47 p for 454 g is a better value.
