Final answer:
To find the price of the air ticket before the festive season, we need to reverse the 15% increase. By setting up an equation and solving for 'x', we find that the original price was $500.
Step-by-step explanation:
To find the price of the air ticket before the festive season, we need to calculate the original price by reversing the increase of 15%. Let's call the original price 'x'. 15% of 'x' is 0.15x.
So, we can set up the equation: 'x' + 0.15x = $575
Combining like terms, we get: 1.15x = $575
To solve for 'x', we divide both sides of the equation by 1.15: x = $500
Therefore, the price of the air ticket before the festive season was $500.
