Answer: Price discrimination
Step-by-step explanation:
Price discrimination refers to a practice where different consumers are charged varying prices based on certain demographic factors.
This practice is very prevalent in insurance due to the various risks that different demographical populations provide. In this instance for instance, the 18 year old is charged higher because young people are known to be more rash when driving owing to them having less experience and being more prone to act impulsively which can lead to accidents.
