Answer 1

By calculating the cost per gram, the 100g packet at £0.081 per gram is found to be slightly cheaper and better value than the 25g packet at £0.082 per gram.

Step-by-step explanation:

To determine which packet of coffee provides better value for money, we need to calculate the cost per gram for each packet. Let's compare the two options:

1. A 100g packet of coffee costs £8.10. To find the cost per gram, we divide the total cost by the number of grams: £8.10 / 100g = £0.081 per gram.
2. A 25g packet of coffee costs £2.05. Similarly, we find the cost per gram: £2.05 / 25g = £0.082 per gram.

Comparing the two costs per gram, we see that the 100g packet costs £0.081 per gram, while the 25g packet costs £0.082 per gram. Therefore, the 100g packet is slightly cheaper per gram and represents a better value for the money.
