You should probably see it in terms of bottom line rather than top line, i.e. the operating margin gained on each sale is about $12M according to wikipedia, so they would need to sell 200 maxes to obtain the net cash they will use to pay the fines.
Sounds like the real punishment should have been the abolishment of the 737 MAX. All the R&D money would be lost and they'd have to start over with a new model.
