Large Jar

Step-by-step explanation:

Large jar - 440g for £1.54

Cost per gram for the large jar = £1.54 : 440g = £0.0035 per gram

Small jar - 340g for £1.26

Cost per gram for the small jar = £1.26: 340g = £0.0037 per gram

Since the cost per gram of the large jar is lower, the large jar offers best value for money.
