I’ve done work for it but my numbers end up not adding up to the total. Please explain this question to me and how I would set it up. Found 3 solutions by josgarithmetic, MathTherapy, ikleyn:Answer by josgarithmetic(39620) (Show Source):

Don't you think it'd have made better sense if you'd also included your work? That way, someone could tell you where you went wrong!
You will find there the lessons for all levels - from introductory to advanced,
and for all methods used - from one equation to two equations and even without equations.
A convenient place to quickly observe these lessons from a "bird flight height" (a top view) is the last lesson in the list.
Read them and become an expert in solution of coin problems.
Believe me that if you read even 1 - 2- 3 lessons from this list, it will be 6 times better,
than if I will solve this single problem for you.
If, from the other side, you read half of lessons from the list, you will become an expert in the area
and will be able to teach others.
