Answer:
600 g of coffee at £7.10.
Explanation:
To determine which option is a better value for money, we can calculate the price per gram for each option.
For 200 g of coffee at £2.40:
Price per gram = £2.40 ÷ 200 g
Price per gram = £0.012 per gram
For 600 g of coffee at £7.10:
Price per gram = £7.10 ÷ 600 g
Price per gram = £0.0118 per gram
Comparing the two prices per gram, we can see that £0.0118 per gram is a lower price than £0.012 per gram. Therefore, 600 g of coffee at £7.10 is a better value for money compared to 200 g of coffee at £2.40.
