Question

(2 mark) A group of 10 friends are planning to a trip. You are responsible for the flight tickets. You searched on the Internet and you found a flight with four different classes. Economy class (100$) has only four available seat, First class (150$) has only 2 available seats, Business class (200$) has only 3 available seats, and Premium class (300$) has 5 available seats. Your budget is limited and you want to save as much as you can. In how many ways you book the tickets?​

Answer 1

4 seats economic, 2 seats first class, 3 seats business class, 1 seat premium class

Explanation:

4 \times economy class = 400$ +

2 \times first class = 300$ +

3 \times bussines class = 600$ +

1 \times premium class = 300$

= 1600$

This is the way to spend the least money if everyone is seated on one seat.
