Teachers are paid $7 per class.

If a class is missed, the fine is $14 per class.

That means the fine is double what the class pays.

So instead of simply losing the $7 earned, a missed class results in a $14 loss.

In practice, this means a single missed class removes the value of two classes worth of pay.

When fines are higher than earnings, it can effectively mean working for free for that time.
