My Favourite D.I.M.C Problem was Scrooge McDuck so the problem was that Scrooge McDuck never spends $1 coins or $10 notes- he saves them. Every now and then he also adds a $50 note to the money he saved. One Day he counts up his savings and discovers that he has saved exactly $550 made up of a total of 50 coins and/or notes.
Find out how many $1.00 coins $10 notes and $50 notes he has saved and prove that this is the only possible solution.
So with my Group we did gusse and check and we use ten nine ten and then we change the the nine with four and we got out of a total of $24 coins/notes and and the exactly $550 but not the coins/notes and the my Group was Lilley Aillie and Jesscia and me Lulu.
