Final answer:
To find the price per kilogram, we divide the price by the weight in kilograms. Both Kostless and Savemore offer the same price per kilogram for Bestcaff coffee jars. Therefore, the correct answer is: a) £1.50 per kg
Step-by-step explanation:
To determine how much per kilogram Kostless's offer is better value for money than Savemore's, we need to compare the price per kilogram at both supermarkets. Both supermarkets are selling a jar of Bestcaff coffee weighing 200g for £2.50. To find the price per kilogram, we divide the price by the weight in kilograms. For Kostless, £2.50 divided by 0.2kg is £12.50 per kilogram. Similarly, for Savemore, £2.50 divided by 0.2kg is also £12.50 per kilogram. Therefore, the difference in price per kilogram between Kostless and Savemore is £0.00 per kilogram. Therefore, the correct answer is: a) £1.50 per kg
