Hi Everyone!

So I’m trying to complete the Cash Register challenge but tbh I don’t understand what I have to do:

each element in the cid array is an array of two elements: the currency unit, namely pennies, nickels, etc. and a number. What is that number supposed to represent? The amount fo nickels, pennies, etc, or the amount in dollars that we have in nickels, pennies, etc?

I’m asking because we are provided with a sort of conversion list from nickles, pennies, etc. to dollars and I’m not sure what the point of that is.

Anyway, I’m suer confused! If anyone can clarify what it is exactly that those elements in the array represent, I’d be super grateful!

Cheers.
