Victoria, happy to help but I struggle to understand the question for now. Can you provide more details as to what you don't understand? 

Also, adding here a resource for common terms that show up in case interviews. Might help you and others as well who stumble upon this case:


Best,
Cristian

Sorry for the inconvenience. I'm referring to the question under analysis 2: Which percentage of customers has to buy the warranty in order to keep WyCar’s profit margin from model “300” stable? I'm confused about how could we get the 80% in the answer?
