$100mm is the list price. Actual prices are decided by the market. I've read about $50mm for the 737-8, the baseline 737MAX model. That was of course before the MCAS disaster. My layman understanding is that actual prices would be around 40% off list price for models that sell really well, with little competition (for instance A321). Much steeper discount above 60% for models that have a hard time selling (A330NEO) or for end of line to close a production gap (777-300ER is very cheap to buy while Boeing is working on the 777-9).
