Answer 2

Calculating the Percentage Change in Ticket Price

To calculate the percentage change in the ticket price, we can use the following formula:

Percentage Change = ((New Price - Old Price) / Old Price) * 100

Given: Old Price = 70р New Price = 100р

Using the formula: Percentage Change = ((100 - 70) / 70) * 100

Calculation

((100 - 70) / 70) * 100 = (30 / 70) * 100 = 0.4286 * 100 = 42.86%

So, the ticket was 42.86% cheaper before the price increase.
