PLEASE HELP URGENTLY

John wants to save money on fuel. His friend tells him: You can save 1/3 of the cost of your fuel by driving efficiently. John spends £72 each week on fuel for his car. He thinks driving efficiently can save him £100 every 4 weeks. Is John correct? Show why you think this us.​

Answer 1

1/3 of 72 = 24
£24 saved each week
24 x 4 = 96
£96 saved every 4 weeks

No, John is not correct. He would save £96 every 4 weeks.
