      It’s much harder to pay complete attention to what you’re writing while trying to teach, that’s why teachers make so many mistakes writing on the board, that’s what the smart kids are for.

    I'm salty. This is a great explanation, but every time I find problems like this, I'm missing both the number of each item used & the total number of all the items. But I wind up expected to solve for both.
    i.e.
    Total Monetary value = known
    Value of individual objects = known
    number of each object = unknown
    total number of all objects = unknown.
