Question

The question is on the ss btw

Answer 1

The shop

Explanation:

Given

Shop

`Cost = E9`

`Bag = 12.5kg`

Supermarket

`Cost=E1.83`

`Bag = 2.5kg`

Required

The better value

To do this, we simply calculate the unit price.

This is calculated as:

`Unit = (Price)/(Bag)`

So, we have:

Shop

`Unit = (9)/(12.5)`

`Unit = 0.72`

Supermarket

`Unit = (1.83)/(2.5)`

`Unit = 0.732`

At the shop, the unit price is £0.72 per bag while at the supermarket, the unit price is £0.732

The best value is at the shop, because it is cheaper

i.e.

`0.72 < 0.732`
