So on the first Friday, $0 minus 42 will be negative $42 daily capital.

And on the second Friday, $140 minus $42

gives us a daily capital of positive 98.

So we can now start filling the total lines.

Our total is simply going to be the previous day plus the current day.

So, Sunday, we have no previous day, so

zero Monday, zero plus zero will stay zero.

We'll just continue this trend across the revenue.

Then finally, on Friday, our total revenues will be

equal to zero for our daily plus 140 for our other.

Zero for our total plus 140 for our daily or $140.

On Saturday, we'll have 140 total revenue on Friday,

zero revenue on Saturdays so that, again, we'll have total $140.

Now, we'll do the same thing for expenses.

So we have 0, 0, 0, 0, 0.

And on Friday, we have $42 of expense.

Continuing our formula, 42 plus 0 across, we'll see expenses of $42 consistently.

Until finally, on a second Friday, we'll see total expenses of $84, and

the same will go for Saturday.
