Answer 1

The percentage increase in price from regular economy to first-class for a round-trip plane ticket from New York to London is 80.8%.

Step-by-step explanation:

To find the percentage increase in price between first-class and regular economy class for a round-trip plane ticket from New York to London, we need to calculate the difference in prices and then divide by the price of the regular economy ticket.
