The pack of 4 has a better value because one toilet roll in a pack of 4 is £0.51 and this can be determined by using the unitary method.
Given :
- Toilet rolls come in packs of 4 and 9.
- The 4 pack is priced at £2.04.
- The 9 pack is priced at £4.68.
The unitary method can be used in order to determine the price per roll. First, the price of one toilet roll in a pack of 4.
If 4 toilet rolls price in a pack of 4 is £2.04 then the price of one toilet roll in a pack of 4 is:
[tex]=\dfrac{2.04}{4}\times 1[/tex]

Now, the price of one toilet roll in the pack of 9. If 9 toilet rolls price in a pack of 9 is £4.68 then the price of one toilet roll in a pack of 9 is:
