Answer: The answer is (22, 15).
Step-by-step explanation: Given that 'x' represents the number of cars Leonard has and 'y' represents the number of cars Liam has.
Then, according to the given information, we have

Answer: the large jar is cheaper
Step-by-step explanation:
If you divide the £1.54 by 440g and £1.26 by 340g, you'll find which one is cheaper per gram :
