BASICALLY THE QUERY IS TO WRITE ALL THE AVAILABLE OPTIONS FOR RON... SO THE LATER SUBQUERY PART SHOULDNT BE COMING IN THIS CONTEXT... SO TECHNICALLY YOU SEE THERE IS SOME MISTAKE WITH THE QUESTIONS
I agree, the instructions are not explicit in asking us to do a subquery to find the minimum coins needed.
Thank you both for pointing out that I need to learn how to do subqueries to get this to work.
I don't know how to do those and I'd never think that I'd have to learn something that hadn't been mentioned in any problem previously to do "basic joins".
