The original price of the ticket was $210 and the new price is $310.
To find the percentage increase, we can use the formula:
percentage increase = (new price - old price) / old price * 100%
So, the percentage increase in the ticket price is:
percentage increase = (310 - 210) / 210 * 100% = 47.62%
Therefore, the ticket price has increased by 47.62%.
If the airline charges an additional $50 baggage fee with the new ticket price of $310, then the new price will be $360.
To find the new percentage increase, we can use the same formula:
percentage increase = (new price - old price) / old price * 100%
So, the percentage increase in the ticket price with the additional $50 baggage fee is:
percentage increase = (360 - 210) / 210 * 100% = 71.43%
Therefore, the ticket price has increased by 71.43% with the additional $50 baggage fee.
