Decision tree can be used as a tool to codify the knowledge for decision making. Read and understand the following scenario.

Mohamed who is a knowledge engineer from Consultant Company used an interview method to understand the flight booking process of ABC Airline Company. He interviews Mr.David who is an experience person and in-charge of the flight booking process in the company. During the interview session, Mohamed documents the business logic that describes the flight booking process of this company. Below is the knowledge he gathered during the interview:

Flight booking can be classified as a favorable and non-favorable day. Favorable day means bookings on that day are high; this always happens during school holidays, festive seasons and during the weekends. While a non-favorable day means the flight bookings on that day are low; this always happens during the weekdays. To encourage bookings and increase the company's profits, ABC Airline Company has made the following rules:

i. During non-favorable dates, flight tickets on these days are reduced by 30% from the normal price.

ii, During favorable dates, the flight ticket on these days is increased by 10% from the normal price if it is fall during the weekdays.
