Step-by-step explanation:
Given:
- Ratio of economy : business : first class = 2:5:9
- Price of a business ticket = $2350
Assume:
- Price of economy class ticket = 2x
- Price of business class ticket = 5x
- Price of first class ticket = 9x
According to question,
=> 5x = 2350
=> x = 2350/5
=> x = 470
Therefore, Price of first class ticket
= 9×470
= $4230
