If the above is factual, then more assistance is required than likely can be provided online, and perhaps better course placement should be considered.

In hopes that the above constitutes hyperbole:

For simplicity's sake, one may start with three hundred and zero, since this clearly represents "three hundred more". How much does Marley have after the seventy days? (Multiply.)

Since Scrooge has no more than this amount after a hundred days, how much, at most, could Scrooge have added over the course of the hundred days? (Subtract.) Then how much could he have been saving each day, at most (as an average)? (Divide.)
