Question

Toilet rolls come in packs of 4 and 9

The 4-pack is £2.04
The 9-pack is £4.68
By calculating the price per roll, determine which pack is better value.

Answer 1

Buy 8 pack with £2.04 and buy 1 pack with £0.52 will be more value

Explanation:

To calculate 1 roll:

2.04/4= £0.51

4.68/9= £0.52

(0.51+0.52)/2= £0.515 = £0.52 per roll

which pack is better value:

2.04 (4 pack) x2= £4.08 for 8 pack

4.08+0.52= £4.6 for 9 pack

£4.6<£4.68

Therefore, buy 8 pack with £2.04 and buy 1 pack with £0.52 will be more value.
