Easy money

Some guy on here gave me this answer but he has used american methods and I am a UK student who is terrible at math. Could someone re-answer this using UK methods to get a simpler answer. Theres no way anyone is gonna believe I did this.

  • "Using UK methods" is very vague! Answering such question will require at least 30 minutes. So you expect someone to work for around $5 an hour and call it easy money?! Good luck getting an answer dude.

  • This must be a joke

  • You might want to attach the method being studied in your course.
